Razer DeathAdder V2 is a great mouse by all accounts. It is a good choice for right-handed gamers and has many advantages such as using the Focus + optical sensor that makes it enjoyable to use.

Just a Glance

The Deathadder V2 Mouse features notable improvements such as its improved optical sensor, more durable left and right mouse buttons, and a smoother and more user-friendly scroll wheel.

A great feature of the Deathadder V2 Mouse is the Focus + Optical Sensor, which is the same sensor used on the excellent Razer Viper Ultimate Wireless.

It also features a wonderful scroll wheel and is very smooth in use, and you will feel its performance when used in various games.

And beautifully, Razer used a new wire, as the only complaint was that the stiffer wire could sometimes pull the mouse to one side.

But the Razer DeathAdder V2 wire is more flexible, light and easy to use and you will not feel any discomfort when using it.

As for mouse settings, Razer Synapse makes it easy to customize Razer DeathAdder V2 to your heart’s content with ease.

You can assign most of its buttons but with the notable exception of the left mouse button, practically any function you want.

For example, if you want to right-click and insert a “$” sign when clicking on it, it can do that.

And if you want to click scroll to start your favorite game, you can simply go through the settings.

It also contains many of the usual customization options as well,

and that includes the ability to set five sensitivity stages that you can navigate through the buttons below the scroll wheel.

You can also assign a value to each of the stages between 100 and 20,000 in 50-step increments, all thanks to the Razer Focus + optical sensor. Polling rate can also be set at 125, 500, or 1000 Hz.

The Razer DeathAdder V2 Mouse has two main buttons, two side buttons, a scroll wheel, and two smaller buttons underneath that play through the DPI presets by default.

RGB-backlit scroll wheel and logo illumination complement the black and gray plastic mouse case.

The Razer DeathAdder V2 Mouse has a relatively large design, as it is made for people with hands older than me.

As for the size, the Razer DeathAdder V2 weighs only 0.18 lbs (81.6 g), so it combines the contour, material and slightly larger dimensions to make it appear larger than it really is.

When testing its use, I found any discomfort that most people could feel.

Trouble using the mouse with either a palm fist.

The DeathAdder V2 mouse is very smooth, although its design makes it a magnet for dust,

but it has more obvious texture aspects and the function of those sides is to prevent it from slipping during use.

As for the scroll wheel, it is also decorative, and it is easy to find among the basic buttons that surround it.

But with DeathAdder V2’s feathered trim it might feel uncomfortable for prolonged use,

for me that didn’t make a good first impression during a long gaming session.


One of the best features of the Razer DeathAdder V2 is the addition of the Focus + optical sensor, which was developed in cooperation with Pixart.

One of the functions of this sensor is that it supports up to 20000 CPI, and this is wonderful by all accounts as it is a huge increase over the relatively small CPI scopes provided by the previous DeathAdder models.

When testing the mouse in games, I did not notice any problems with tracking the mouse when testing multiple games (Call of Duty, PUBG), regardless of the CPI setting I used. Every movement was smooth, fast, and without any interruptions too, which is something I can’t say for the Sensei 310 that I usually use.

The DeathAdder V2’s basic buttons were responsive enough that I was extremely enjoying the movement and any controls in the game.

The only drawback that I found during testing was the side buttons.

I wasn’t sure I pressed them hard enough while playing, it could be because of the large size.

As for the scroll wheel in the DeathAdder V2 mouse, it is very smooth as it can be scrolled enough in-game to move between weapons.

Another feature of the DeathAdder V2 Mouse was the “Razer Speedflex” braided cable for connecting to the computer.

It was easy to use and never distracted me while gaming. There was no drag, as it was lightweight.

Our Verdict

The Razer DeathAdder V2 Mouse is suitable for people with large hands

and people who also require a lot of customizable devices, as it has a set of side buttons.

It is intended for people who want solid performance for gaming.

It also has great features such as the Razor’s Focus + optical sensor and the lightweight

and comfortable Braided Speedflex cable that make a great combination.
