Design

The Razer DeathAdder v2 Pro is slightly larger and heavier than the Razer Viper Ultimate.

The Razer DeathAdder v2 Pro (left) is for right-handed users while the Razer Viper Ultimate (right) can be used by both left and right-handed users.

These two gaming mice are similar in a lot of ways, but not in their design. The Razer DeathAdder v2 Pro has a right-handed orientation and its buttons are placed in optimal positions so you can use them all without straining. In contrast, the Razer Viper Ultimate has an ambidextrous design so it can be used by both left and right-handed users. A flaw in its design is that it has thumb buttons on both sides, so the buttons that are on the opposite side of your thumb can be hard to click.

They are about the same length, but the Razer DeathAdder v2 Pro is a little bit wider and taller. It is more suited for those with bigger hands as its bulkiness can be uncomfortable for those with smaller hands. The Razer DeathAdder V2 Pro is also a bit heavier, weighing 88 grams to the 74 grams of the Razer Viper Ultimate.

They are both made from solid plastic but they feel sturdy and durable. If you travel a lot, you can bring either gaming mice with you since they are very portable. They have compartments at the bottom for their wireless receivers so you don’t have to worry about losing them.

Features and Connectivity

Both the Razer DeathAdder v2 Pro and Razer Viper Ultimate have wired and 2.4GHz modes, but the former also has Bluetooth connectivity.

The Razer DeathAdder v2 Pro and Viper Ultimate have similar optical sensors and switches.

When it comes to features, they are very similar. Everything that can be adjusted, such as remapping buttons, RGB lighting, sensitivity adjustments and so on, can be done using the Razer Synapse 3 software. You can adjust the sensitivity for both mice to a max of 20000 DPI with five different stages and you can cycle between these five stages using their DPI buttons.

These two gaming mice have 8 programmable buttons that you can remap to pretty much any key or function. You can also create macros if you like, so there are a lot of tweaks that you can do using the Razer Synapse 3 software. Once you’ve created a custom button profile, you can save it to their on-board memory (up to 5).

Both gaming mice are also compatible with Razer Chroma, so you can adjust the lighting effects to sync up with other Razer devices, assign an individual effect for each or just disable the RGB if you don’t like it. There are many customizations available to you inside the Razer Synapse 3 software.

As far as connectivity goes, both mice have wired and wireless 2.4GHz HyperSpeed mode. However, the Razer DeathAdder v2 Pro comes with an additional Bluetooth mode. The benefits of its Bluetooth mode are that you can pair it to two devices simultaneously for multi-tasking and that it is able to conserve battery more.

Performance

You can adjust their sensitivity inside the Razer Synapse 3 software and set five different stages that you can cycle through while gaming, so that you have the best sensitivity setting in any situation.

The Razer DeathAdder v2 Pro and Viper Ultimate also have the same polling rate choices—125Hz, 500Hz and 1000Hz. The lift off distance for both is also adjustable within the Razer Synapse 3 software. They are pretty much the same when it comes to performance.

These mice are designed with FPS players in mind. They are excellent for FPS games, third person action/adventure games and other games that require precision, fast reflexes and twitch movements. Of course, you can still use them for more casual games or games that don’t require precision and fast movements.

For office or regular use, the Razer DeathAdder v2 Pro has an advantage over the Viper Ultimate since it has a Bluetooth connection mode that allows you to pair it to up to two devices simultaneously. Also, its Bluetooth mode can extend its battery life, so you don’t have to worry about charging it often.
