On this page I’ll be comparing the Razer Viper vs Glorious Model O. Both of these mice were released this year and are chasing the same goal: to be the ultimate lightweight gaming mouse. The Viper is now Razer’s lightest gaming mouse by a longshot with the previous lightest being the Abyssus V2 at 83 grams. The Glorious Model O, on the other hand, is even lighter than the viper weighing just 67 grams. If you’re in the market for a lightweight mouse then there’s a good chance you end up choosing between these two. Hopefully this page helps you decide which is best suited for you.
Glorious Model O
Mouse review: Razer Viper
Razer have officially entered the lightweight gaming mouse market with the newly released Razer Viper. The mouse weighs just under 70 grams making it Razer’s lightest mouse by a long shot, their lightest mouse before the Viper would be the Razer Abyssus weighing 83 grams. Lightweight gaming mice have had a recent boost in popularity so it was only a matter of time before Razer made their own. Razer have designed this mouse with esports in mind, I could see a lot of both casual and competitive gamers using the Viper as their main mouse.
Shape and design
It’s a medium-sized mouse with an ambidextrous shape, low profile, and plenty of comfort curves. The low profile makes it best suited for a claw or fingertip grip style, this does depend on your hand size of course. Each side has rubberized grips for improved grip and comfort, the sides are also slightly curved for the same reason.
Razer have used their speedflex cable for this mouse, it’s ultra-smooth and highly flexible. When paired up with a mouse bungee the Razer Viper should feel almost wireless.
Like most Razer mice, the Razer Viper has an all-black design with a Razer logo on the backside of the shell. The logo has RGB backlighting which can be customized using Razer Synapse. Overall it has a pretty minimal design when compared to other gaming mice on the market.
Extra buttons and optical switches
Both of the primary click buttons have Razer Optical Switches and they come with a few notable benefits:
- 40% Longer lifespan compared to traditional switches
- 3x Faster actuation
- Zero double-clicking issues
Razer have put two side buttons on each side to stay true to the ambidextrous design. They are standard side buttons placed just above where your thumb would rest. Having buttons on both sides may take some getting used to, thankfully, Razer designed them in a way that shouldn’t affect the comfort of the mouse.
Unlike most gaming mice, the DPI button on the Razer Viper is on the bottom of the mouse rather than the top. This means you cannot change your DPI on the fly, although it is nice to have it placed out of the way.
The Razer Viper has an amazing optical sensor with near-flawless tracking, you should have no sensors issues when using this mouse. The DPI can be adjusted in steps of 50 with the max being 16,000 and the minimum being 100.
Like all Razer mice, you can use the Razer Synapse software to adjust all of the important settings for the mouse. A few examples of these settings are the DPI, RGB lighting, macros, and profiles. The Razer Viper has on-board memory so you only have to configure your settings once, this is great for people who travel with their mice.
Razer Viper Ultimate – 74 grams & wireless
There is now a wireless version of the mouse available called the Razer Viper Ultimate. It’s only slightly heavier than the wired version weighing just 74 grams, this makes it possibly the lightest wireless gaming mouse in the world.
Other than the fact that it’s wireless, there is only one key difference between this mouse and the original, and it’s the sensor. The Viper Ultimate uses Razer’s new FOCUS+ sensor which was designed with wireless gaming in mind, it has a slightly higher max DPI of 20,000. Much like the G Pro, the Viper Ultimate has a near flawless wireless connection so you’ll see no issues there.
It has an impressive 70 hour battery life with the lights turned off, but keeping the lights on will cut this down significantly. In the box you’ll get an RGB charging dock, the wireless adapter, and a charging cable. While the Viper Ultimate is an amazing mouse, there is one obvious drawback… the price. It’s $150 as of writing this which is a lot more than most people are willing to spend on a mouse. Although, if you’re looking for the lightest wireless gaming mouse, then the Razer Viper Ultimate is the clear winner.
Mouse review: Glorious Model O
The Glorious Model O is fairly new to the market but is already attracting tonnes of attention. The mouse has a similar design to the Finalmouse Air58 which also had a lot of hype when it was first released. The Model O weighs 67 grams making it one of the lightest gaming mice money can buy. Lightweight gaming mice have become very popular recently, Glorious have realized this and have made this impressive mouse in response. Glorious do not currently sell their mice on Amazon but you can order the mouse through their website with worldwide shipping available.
Shape and design
The shape of a mouse is extremely important and a mouse is only good if you find it comfortable. Thankfully this mouse has a great ambidextrous shape and it’s clear Glorious have put a lot of thought into it. The mouse shape is very similar to the Zowie FK1 which is good news as the FK1 is loved by many. It’s a medium-sized mouse with a low profile. The shape of the mouse makes it ideal for fingertip and claw grip styles, people with smaller hands could palm grip the mouse if they wanted to.
You can choose from 4 different designs when buying this mouse: black (matte), white (matte), black (glossy) & white (glossy. It’s nice to have the option between matte or glossy as everyone has their own personal preference. There’s a Glorious logo on the left side of the mouse which is small and not intrusive. The braided mouse cable is ultra-flexible and lightweight making the mouse feel practically wireless. The G-Skates mouse feet are designed to let your mouse glide across the mousepad, they are 0.81mm thick giving them a long lifespan.
The HoneyComb shell is the key to the Model O’s impressively lightweight. Having holes throughout the shell dramatically reduces the weight while barely affecting the feel of the mouse. Finalmouse may have popularised this design but their mice are famously difficult to buy and are pretty expensive. Glorious have managed to pull off this design while keeping the mouse relatively cheap at $49.99. This design makes the mouse look fragile but Glorious ensure that this is not the case. The mouse is durable and should hold up just as well as any other gaming mouse.
There are two side buttons on the left-hand side of the mouse. Two side buttons is the standard for FPS gaming mice and can help a lot with extra keybinds. The buttons are thin and placed out of the way from your thumb. Each button is easy to click while still providing a crisp tactile feedback. There is also a DPI button below the scroll wheel, this DPI button is pretty small compared to other gaming mice. A small DPI button can actually be a good thing as it makes it less likely to be missclicked.
The Pixart 3360 sensor has been designed with esports in mind and has a near-perfect performance. It has a maximum DPI of 12,000 which can be adjusted in steps of 100, the minimum DPI is 400. Glorious promise pixel-perfect tracking, zero mouse acceleration, no spinouts, and a less than 0.7mm lift-off distance.
Lighting and software
The Glorious Model O has full RGB backlighting making it the world’s lightest RGB gaming mouse. You can choose from a bunch of different lighting effects or simply go with a solid color. The RGB lighting is found in 3 locations: two thin strips on both sides of the mouse as well as a backlit ring around the scroll wheel.
The mouse can be used without any software making it a driver-free plug and play gaming mouse. Software is available for anyone who wants to customize the mouse a little further. Using the software you can adjust all of the usual settings such as your DPI profiles and macros.
Razer Viper vs Glorious Model O
Both of these mice are high quality, lightweight, and perfect for competitive gaming. It’s up to you to weigh up the pros and cons of each mouse and compare them to your personal preferences. The most important things to consider are the price, shape, design, and weight of the mice. I hope this page has helped you understand the differences between these two mice.
