Razer Viper vs Logitech G Pro Wireless | Mouse Review

On this page I’ll be comparing the Razer Viper vs the Logitech G Pro Wireless. The Viper is a new release from Razer and it is now their lightest gaming mouse by a longshot. Logitech’s G Pro, on the other hand, has been around for a while now but still remains a popular choice. If you’re in the market for a lightweight gaming mouse then you may end up choosing between these two mice. Hopefully this page will help you decide which mouse is the best choice for you.

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.

Mouse sensor

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.

Razer synapse

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: Logitech G Pro Wireless

The G Pro Wireless is part of Logitech’s Pro series and is extremely popular amongst both serious and casual gamers. It’s a wireless medium-sized mouse with a low weight of 80 grams. Wireless mice are no longer considered worse than wired mice. Many pro esports players are currently using the G Pro in tournaments, this alone should be enough proof of the wireless capability. Logitech spent 2 years receiving and reviewing input from over 50 pro esports players before releasing the G Pro Wireless, and as a result have built an almost perfect mouse. Naturally, this mouse is going to cost a fair amount more than a wired gaming mouse.

Shape and design

The Logitech G Pro Wireless has a great ambidextrous shape best suited for claw and fingertip grip styles. It’s a medium-sized mouse with similar dimensions to the Razer Viper, although it is slightly taller. Both sides of the mouse are slightly curved to assist lift-off gameplay and comfort. More comfort grooves can be found on both of the primary click buttons which I’m always a fan of. Overall the G Pro Wireless has a nice ergonomic shape and should be comfortable for long gaming sessions.

Logitech have gone with a minimalistic design for the G Pro. It’s an all-black mouse with a backlit RGB Logitech logo on the bottom half. I personally love the look of this mouse and it’s a nice change from the usual gaming mouse style. The whole shell is plastic and very sturdy so the mouse should last a very long time. There is a small compartment on the bottom side of the mouse which is the perfect place to store the USB receiver. You could also place a weight in the compartment if 80 grams is too light for you.


Logitech have the best wireless products in the gaming industry thanks to their lightspeed technology. The G Pro has a 1ms report rate and will feel no different from a wired mouse. At full charge, the mouse will last 50 hours with lighting and 63 hours with no lighting. Playing without a wire can make your gameplay feel so much smoother, wire drag causes friction and can be distracting. Multiple esport pros use wireless Logitech mice for tournament-level play. Wireless Logitech mice were the first wireless mice to be used in official CSGO tournaments, if it’s good enough for the pros, it’s good enough for anyone!

Extra buttons

There are four mechanical side buttons on the G Pro Wireless, two on each side. These buttons are completely optional as they can be removed and replaced with covers. Customizable side buttons are perfect for an ambidextrous mouse as you have full control of the layout. You can use the Logitech G Shift setting to set one of the buttons as a modifier, this essentially doubles the functions on the mouse. Four side buttons combined with the G Shift setting makes the G Pro a decent choice for MMO games. Much like the Razer Viper, the DPI button on the G Pro is on the bottom of the mouse meaning you’ll never click it by accident.

Mouse sensor

The G Pro Wireless is equipped with Logitech’s most accurate gaming sensor, the HERO 16K. It has a 100 to 16,000 DPI range which can be adjusted in steps of 50. The HERO 16K delivers perfect performance at any sensitivity with zero acceleration or smoothing. This is about as good as gaming sensors get, you will have no sensor issues when using this mouse. The HERO 16K uses 10x less power than its predecessors which is partly responsible for the G Pros amazing battery life.

You can use the Logitech Gaming Software to customize all of the important settings on the mouse. It’s a simple program and should be fairly easy to understand, it’s really up to you how complicated you want to make it. Like most Logitech gaming mice, you can store all of your settings on-board the mouse making it plug-and-play after the first setup.

Razer Viper vs Logitech G Pro

These are two great gaming mice with a few similarities as well as some notable differences. Both mice are lightweight and perfect for both casual and competitive gaming. Either of these mice would be a good choice, it’s up to you to compare the pros and cons to your personal preferences. The main things to consider are the price, shape, design, and weight of the mice.
