The Lightest Gaming Mice – Updated for Summer 2021

Ever since the release of the Finalmouse Air58 back in 2018, gaming companies have been competing with each other to create the perfect ultra-light gaming mouse. In this post, I’ll be reviewing and comparing the sixteen lightest gaming mice for 2021. All of the mice on this list weigh less than 70 grams, have top-tier components, and are made by a reputable brand. 

Keep in mind that this list is only ordered by weight, the best mouse for you will depend on your personal preferences, number one on this list is not necessarily better than number sixteen!

Why go ultra-light?

People use ultra-light mice because they find them easier to aim with, it’s really that simple. The lighter the mouse, the easier it will be to start and stop. If you browse through a site like, you’ll start to notice just how many pro players use an ultra-light mouse, with the majority using a mouse under 80 grams.

That being said, you shouldn’t sacrifice the other key aspects of a mouse just because you found one that weighs less. The shape of a mouse should always come first, there’s no use in having a 50g mouse if you’re uncomfortable while using it. So although the weight of a mouse is significant, you should also consider the shape, specs, build quality, and price.

1. Cooler Master MM720

Cooler Master MM720 - The Lightest Gaming Mouse

49g • Pixart 3389 sensor • 105x77x37mm •  RGB • ultraweave cable

The first and lightest mouse on this list is the MM720 from Cooler Master. Weighing just 49 grams It’s one of the lightest gaming mice on the market.

The MM720 has a unique shape compared to the other mice on this list. It has a short yet wide ergonomic design with a ledge to rest your ring finger on. Cooler Master confirmed that the shape was designed with a claw grip style in mind, if you don’t use a claw grip I would recommend checking out the MM710 instead. If you’re unsure what grip style you use, check out my grip style post here!

Under the hood the mouse has everything you would hope for; a top-tier Pixart sensor, optical switches, and 2-zone RGB lighting. While the honeycomb shell is a big influence on the low weight, a lot of people worry about the potential downsides, like dirt and water damage. Thankfully, the PCBA has been sprayed with dust and water-resistant coating, preventing any honeycomb-related malfunctions. 

The new ultraweave cable combined with the 95% PTFE mouse skates gives the mouse an almost wireless feel, the days of stiff plastic cables are truly behind us. Lastly, there are four designs to choose from including; matte black, matte white, glossy black, and glossy white.

2. G-Wolves Hati HTM S

G Wolves Hati HTM Review and specs

50g • Pixart 3360 sensor • 113x61x40mm •  Paracord cable

G-Wolves have managed to emulate the Finalmouse style but without limited availability and at half the cost. The Hati HTM S has a very similar shape to the Logitech G PRO, a mouse that has been a fan favourite ever since its release. The symmetrical shape and small size make it perfect for a fingertip grip style, if you prefer a palm grip you might want to go for the regular HTM rather than the HTM S.

Thanks to the small size and the honeycomb shell, the Hati HTM S weighs an impressive 50g. The regular HTM is 11mm longer and 3mm wider than the HTM S, while this may sound minimal, it ends up adding 11g to the weight making it 61 grams, which of course is still an ultra-light mouse.

Aside from the shape and size, the G-Wolves Hati is equipped with a flawless Pixart sensor, PTFE mouse skates, and a detachable paracord flex cable. There are currently 5 unique design options on Amazon US but it seems that a few of the colours are limited in stock, this is sadly a common issue when it comes to mice with multiple colours.

An extra cool thing about this mouse is the generous amount of accessories it comes with. Along with the mouse you’ll receive some anti-slip grip tape, a tin collectors box, a cleaning brush, and a spare set of mouse skates!

3. Cooler Master MM710

Cooler Master MM710 - The best ultra-light gaming mouse

53g • Pixart 3389 sensor • 117x63x38mm •  ultraweave cable

The Cooler Master MM710 is very similar to the MM720 at the top of this list, they share the same honeycomb design as well as the top-tier sensor, cable, and mouse skates. The key difference between the two mice is the shape. The MM710 has a more traditional symmetrical shape making it suitable for a wider range of hand sizes and grip styles. For example I use a fingertip grip, so if I had to choose between the two mice I would go for the 710.

The MM710 has four designs to choose from; matte black, matte white, glossy black, and glossy white. There’s also an alternative RGB edition available called the MM711 which has an exclusive green design dubbed “Wilderness”. Keep in mind the RGB version weighs 60 grams making it 7 grams heavier than the original.

4. Xtrfy MZ1 – Zy’s Rail

57g • Pixart 3389 sensor • 111x53x37mm •  EZcord Pro cable

Xtrfy and Rocket Jump Ninja have teamed up to design the ultimate lightweight fingertip grip mouse. If you’re not familiar with RJN, he’s considered to be the world’s top mouse reviewer. With 20 years of FPS experience and more than 150 mouse reviews on his channel, he’s earned his reputation. RJN has always gravitated towards ultra-light mice, so naturally his first signature mouse is incredibly light at just 57 grams.

If you’ve watched any of Zy’s mouse reviews you’ll know that shape is his top priority. He said he was tired of companies simply mirroring each other’s shapes, so he stepped up to the challenge and put his own theories to work. Zy says it himself, the shape is not for everyone, but the people who like it, love it. Here’s what he had to say about the design:

“I decided to test some theories of what would make the best mouse: a thin grip width, low button height, high back, subtle curvature on the sides, comfort grooves in the buttons, and more. And thankfully, the theories were right. I’ve never aimed better.”

As you would expect, both the build-quality and the specs of the mouse are top-tier quality. It has a flawless Pixart sensor, splash & dust resistant components, 100% PTFE mouse skates, a flexible braided cable, and RGB lighting. Lastly it’s a “plug and play” mouse with no software required, all of the settings can be adjusted using the buttons hidden below.

5. SteelSeries Aerox 3

SteelSeries Aerox 3 - dimensions and review

57g • TrueMove Core sensor • 121x58x38mm •  Super Mesh cable

SteelSeries have successfully entered the ultra-light meta with their release of the Aerox 3 and the Aerox 3 Wireless. The wired version weighs 57 grams making it easily the lightest mouse we’ve seen from SteelSeries. Like most mice in the under 60 club, the Aerox 3 has a slim honeycomb shell. SteelSeries stated that they managed to shave off 18 grams on the shell alone. You won’t have to worry about any hole-related damages as the Aerox 3 is the first gaming mouse to be entirely IP54 water and dust-resistant.

It’s equipped with a top-tier sensor as well as three-zone RGB lighting, PTFE mouse skates, and a high-quality cable. The new Super Mesh USB-C cable is lightweight, flexible, and detachable.

Aerox 3 Wireless – 66 grams

There’s also a wireless version available with all of the same specs and qualities of the original, the only difference being the weight and price tag. The Aerox 3 Wireless weighs 66 grams, making it 9 grams heavier than its wired counterpart. It’s still one of the lightest wireless gaming mice on the market and is certainly an ultra-light mouse. Although that comes with a cost, It’s 50% more expensive than the wired version as of writing this review.Top-tier wireless mice are no longer considered worse for performance, and this includes the Aerox 3. The Quantum 2.0 Wireless is stable, reliable, and efficient. It boasts an 80 hour battery life in the 2.4GHz mode and up to 200 hours in Bluetooth.

6. Glorious Model O Minus

Glorious Model O Minus Ultra-light gaming mouse

58g • Pixart 3360 sensor • 120x58x36mm •  Ascended Cord cable

Glorious were early adopters of the ultra-light style with the release of the original Model O back in 2019. Fast forward to 2021 and there’s now two additional versions of the mouse, the Model O Minus, and the Model O Wireless. The symmetrical shape and multiple sizes make the mouse a strong contender for all grip styles.

As the name suggests, the Model O Minus is an extra-small gaming mouse weighing a tiny 58 grams, 9 grams less than the standard size. It has full RGB lighting and four designs to choose from; matte black, matte white, glossy black, and glossy white. 

Glorious have said themselves that the Model O was designed to be used at a competitive level, and the specs reflect that. The Pixart 3360 sensor is flawless, the cable is light and flexible, and the G-Skates are made of 100% PTFE. Lastly, while there is software available for the Model O, it’s entirely optional as all of the settings can be changed via the mouse itself, making it driver-free.

The regular Model O

The regular Model O shares the same shape and specs as the Minus, the only difference being the dimensions and the weight. It weighs 67 grams making it 9 grams heavier than the Minus. It’s considered a medium-sized mouse with the dimensions being 128x59x37mm.

The Model O Wireless

The newest edition to the series is the Model O Wireless. Despite having the same dimensions and specs as the regular Model O, it’s somehow only 2 grams heavier at 69g. The 2.4GHz wireless is lag-free and indistinguishable from its wired competitors. It has an impressive 70+ hour battery life (with the RGB switched off) and can be used while being charged thanks to the flexible USB-C cable. The downside as you may have guessed is the price, depending on where you buy the mouse it can be almost double the price of the original.

7. HyperX Pulsefire Haste


59g • Pixart 3335 sensor • 124x67x38mm •  HyperFlex cable

HyperX have also joined the ultra-light wave with the release of the 59 gram Pulsefire Haste. Like all of the under 60g mice on this list, the Pulsefire Haste has a honeycomb shell to drastically reduce the weight. It’s a medium-sized mouse with a safe symmetrical shape making it suitable for a wide range of grip styles and hand sizes.

When it comes to the specs and build quality, this mouse has everything you need. It’s equipped with a top-tier Pixart sensor, 100% PTFE skates, dust-proof switches, and a HyperFlex paracord cable. There’s also an extra pair of mouse feet in the box as well as optional grip tape for the sides and mouse buttons.

8. Razer Viper Mini

Viper Mini vs Regular vs Ultimate

60g • Razer 3359 sensor • 118x54x38mm •  Speedflex cable

The Razer Viper Mini is a smaller and lighter version of the original Viper. It weighs 61 grams making it 8 grams lighter than the standard Viper, and 13 grams lighter than the wireless Viper. Much like the Razer Orochi V2, the Viper Mini has managed to achieve an ultra-light weight without using a honeycomb shell. The mouse has a safe symmetrical ambidex shape making it suitable for all grip styles, although people with large hands may prefer the standard size over the Mini.

All 3 versions of the Viper have a flawless sensor, a Speedflex cable, 100% PTFE mouse feet, and Razer optical switches. The RGB underglow on the other hand can only be found on the Viper Mini.

At just under $40 as of writing this, the Razer Viper Mini is in my opinion the best budget ultra-light gaming mouse. It’s about half the price of the regular version with the only notable difference being the size.

The regular Razer Viper – 69 grams

The regular Razer Viper shares the same shape and specs with the Mini, the only difference being the dimensions and the weight. It weighs 69 grams making it 8 grams heavier than the Mini. It’s considered a medium-sized mouse with the dimensions being 127x66x38mm.

The Razer Viper Ultimate (wireless) – 74 grams

The Viper Ultimate has the same dimensions as the regular Viper and weighs 74 grams which is impressively light for a wireless gaming mouse. It uses Razer’s flawless HyperSpeed wireless technology making it feel no different to a wired connection. The mouse has a 70 hour battery life and can be charged using either the charging dock or the Speedflex charging cable, both included in the box. The obvious drawback to the Ultimate is the price, as of writing this it’s almost 3x the cost of the Viper Mini.

9. Glorious Model D Minus

Glorious Model D Minus review

61g • Pixart 3360 sensor • 120x67x40mm •  Ascended Cord cable

The Model D has the same build quality and specs as the Model O but with an ergonomic asymmetrical shape rather than the symmetrical ambidex style. The ergonomic shape makes it perfect for a palm grip style. It’s available in two sizes; the Model D and the Model D minus. The Minus is the lighter option, it weighs 61 grams making it 7 grams lighter than the original.

In case you missed the specs on the Model O, the Model D is equipped with a flawless Pixart sensor, an ultra-flex cable, and 100% PTFE mouse feet. All of the settings can be adjusted via the mouse itself making the software entirely optional.

Like all Glorious mice, the Model D has two colours and materials to choose from; black, white, glossy, and matte.

10. Razer DeathAdder V2 Mini

62g • Razer 3359 sensor • 114x65x39mm •  SpeedFlex cable

The Razer DeathAdder is quite possibly the best-selling gaming mouse of all time. One of the newest editions to the series is the DeathAdder V2 Mini. It weighs 62 grams making it 20 grams lighter than the standard V2, and 28 grams lighter than the V2 Wireless. It’s a small mouse with an ergonomic right-handed form factor. I see it as an ergonomic alternative to the Viper Mini, similar to the Glorious Model O vs the Model D.

It shares the same top-tier specs and build-quality as the Razer Viper Mini making it suitable for both casual and competitive gaming. The mouse has a flawless sensor, a Speedflex cable, 100% PTFE mouse feet, and optical switches. It also comes with a set of anti-slip grip tape that can be applied to the top and sides of the mouse.

The best part about the Mini Razer mice is how cheap they are. For some reason Razer have made both the Viper Mini and the DeathAdder Mini over half the price of their standard versions. The reason this is surprising is because the specs and build quality of the two versions are practically the same, the only notable difference is the size. As someone who prefers small mice It’s confusing, but I’m certainly not complaining.


Logitech G PRO X SUPERLIGHT comparison

63g • HERO 25K sensor • 125x64x40mm •  wireless

The G PRO X Superlight is 25% lighter than the original weighing just 63 grams, down from 80g on the G PRO. It shares the same shape and dimensions as the original, making it a medium-sized ambidex mouse. Unlike the original, it no longer has side buttons on both sides, just the left. Logitech have also upgraded the mouse feet to 100% PTFE material making the mouse smoother than ever.

As for the specs, the G PRO X has the same flawless HERO sensor as the original, as well as pro-grade LIGHTSPEED wireless. It has a 70 hour battery life and can be charged with the USB cable included. Unfortunately, unlike the Viper and Model O, Logitech have opted for a rubber cable instead of a braided flex cable, but for a wireless mouse this isn’t a huge deal. The mouse is also compatible with the Logitech POWERPLAY mousepad (sold separately!) which will keep it charged at all times.

12. Razer Orochi V2


64g • Razer 3335 sensor • 108x60x38mm •  wireless

To clear up any confusion, the weight of this mouse will vary depending on what batteries you use, the 64 grams is achieved by using a AAA lithium battery. That being said, it’s still going to be super light no matter what battery you go for.

The Orochi V2 is a small wireless gaming mouse with an impressively low weight of 64 grams. It uses Razer’s HyperSpeed wireless, giving you a flawless connection that’s no different from a wired experience. Razer decided to ditch RGB lighting in favour of a longer battery which has clearly paid off. The Orochi V2 has an insane battery life, it can last up to 425 hours in HyperSpeed mode and almost 1000 hours while on Bluetooth.

The mouse is available in both black or white on Amazon, but if you order the mouse from Razer’s own site you can customize your own personal design at an extra cost. As for the specs, the sensor is flawless, the mouse feet are 100% PTFE, and the switches have a 60 million click lifespan.

13. ROCCAT Kone Pure Ultra

66g • ROCCAT Owl-Eye sensor • 115x70x39mm •  standard rubber cable

ROCCAT have taken the original Kone Pure and made it 22 grams lighter with the release of the Kone Pure Ultra. The mouse weighs 66 grams making it the lightest mouse we’ve seen from ROCCAT. It’s a medium-sized mouse with a right-handed ergonomic shape. Not shown in the picture above is the deep thumb groove on the left side of the mouse for extra grip and comfort. Like a lot of ROCCAT mice, the Kone Pure Ultra is available in both black and white.

Where the mouse is potentially lacking is the standard mouse feet and rubber cable. With it being priced above mice like the Viper Mini and the Model O, you would expect to at least meet the same standards. That being said, if the unique ergonomic shape appeals to you it’s still a mouse worth checking out.

14. ROCCAT Burst Pro

68g • ROCCAT Owl-Eye sensor • 120x58x39mm •  PhantomFlex cable

Another mouse from ROCCAT, only 2 grams heavier than the last, is the ROCCAT Burst Pro. It’s a medium-sized mouse with a symmetrical ambidex shape and weighs 68 grams. ROCCAT have opted to keep all of the weight-reducing holes underneath the top layer, and while this does cost them some weight, it saves you from worrying about dust or water damage. Having the RGB lighting underneath the translucent top layer gives off a pretty cool effect. The Burst Pro is also available in either black or white.

Unlike the Pure Ultra above, the Burst Pro is equipped with both a PhantomFlex cable as well as 100% PTFE mouse feet, even though it’s a little cheaper. So if you’re choosing between the two ROCCAT mice and like both shapes, I would go for the Burst Pro for those two improvements alone.

15. SteelSeries Prime

69g • TrueMove Pro sensor • 125x59x42mm •  Super Mesh cable

There are three versions of this mouse to choose from; Prime, Prime+, and Prime Wireless. All three versions share the same medium-sized dimensions and ergonomic shape. The lightest version is the regular Prime at 69 grams, the Prime+ is a close second being only 3 grams heavier. The only notable difference is the Prime+ having an OLED screen and a slightly improved sensor. The question to ask is whether these extra features are worth an additional 3 grams as well as a 30% price increase.

All three versions have a flawless sensor, a detachable super mesh cable, RGB lighting, and a textured matte finish.

SteelSeries Prime Wireless

The Prime Wireless is the heaviest version coming in at 80 grams, still relatively lightweight for a wireless gaming mouse. The Quantum 2.0 Wireless is flawless and indistinguishable from a wired connection. SteelSeries have 1-upped the competition with a 100 hour battery life, just 15 minutes of charge time will net you 40 hours of gameplay. For some reason, the Prime Wireless is also the only version of the mouse to have 100% PTFE mouse feet.



70g • Pixart 3370 sensor • 122x66x38mm •  Flex Cord 2.0 cable

The XM1r is a medium-sized ultra-light gaming mouse with no holes, an ambidex shape, and a weight of 70 grams. The mouse is equipped with a new and improved flex cord, PTFE mouse skates, and a flawless Pixart sensor. There are a few designs to choose from, my favourite being the translucent “Dark Reflex” one, which looks even cooler on the RGB version of the mouse. Overall, the XM1r is a reasonably priced lightweight mouse with a nice shape, top-tier specs, and a low-key design.

Frequently asked questions

Honeycomb concerns: dirt, dust, and water

Having holes on a mouse exposes it to the outside world, and you can’t blame anyone for being concerned about the consequences. Thankfully the companies making these mice have done everything they can to eliminate the risk of damage.

The Aerox 3 for example has been applied with a special coating making it entirely IP54 dust & water-resistant. SteelSeries have also strategically designed the click switches to prevent any dust or dirt from working their way inside. 

If you’re still worried about the risks of a honeycomb shell, I recommend reading this article SteelSeries wrote on the topic: How We Made the Aerox Mouse Ultra Lightweight

If you want to know how to keep a honeycomb mouse clean, here’s a great video of someone cleaning the Model O: How to clean the Glorious Model O or O- Mouse

Are ultra-light mice worth it?

If your goal is to aim as well as possible, then yes I think they are worth it, or at the very least worth a try. There’s a reason so many pro players are using ultra-light mice, they simply find them easier to aim with. With plenty of affordable options available, you no longer have to spend $70+ to get hold of an ultra-light mouse. But ultimately it’s going to be up to you whether they’re worth it or not, the best thing you can do is watch a bunch of reviews and ask around.

Where are the Finalmouse mice?

I chose to not include Finalmouse products as they are infamously hard to get hold of, as well as up to triple the price of the alternatives. I don’t think it would be helpful to the reader to have a mouse that is almost always out of stock at the top of the list. That being said, they do make some of the lightest gaming mice on the market, so if you’re not put off by the price and limited availability then they are still a top choice.

Speaking of lightweight, expensive, and hard-to-buy mice, there’s one more mouse I chose not to include, which also happens to be the lightest gaming mouse in production. The Zaunkoenig M2K is a bizarre looking ultra-light gaming mouse with no holes, top-tier specs, and an unbelievable weight of 24 grams. I honestly wish I could try this mouse myself, but at €299 I think I’ll have to pass. You can find out more about the M2K here: The fastest gun in the West.
