Click latency is very small, and CPI can be freely set over a wide range. All buttons are reprogrammable and comfortable enough to withstand long gaming marathons. It is ideal for palm grips of any hand size, although those with smaller hands may struggle with claw and fingertip grip. The biggest selling point of the DeathAdder V2 is its ergonomic design. The body is curved to follow the natural movement of the hand, and the left and right click buttons are contoured for comfort. The left and right click buttons use Razer’s proprietary infrared laser switches instead of traditional membrane or Omron mechanical switches. The laser beam and the gate attached to each button work together to recognize the click with a response time as short as 0.2 milliseconds. The laser and gate system also prevents accidental half-presses when adjusting grips or changing movements during a game. Because the switches are not mechanical, the clicks feel a bit softer than on other Razer models and other brands. This makes the DeathAdder V2 a little more muted while working or gaming, making it ideal for collaborative work or gaming spaces where you might want to give your coworkers or teammates extra noise. The sensitivity up/down buttons have also been redesigned; the Elite had one elongated button split into two; the buttons on the V2 are wider and separated by a single piece of plastic. It’s not fancy looking, but the gap makes it easier to distinguish between the two without looking, ideal if you need to change sensitivity during combat (e.g., if you’re a sniper and zoom in). Also on the bottom of the mouse is a new button that toggles between custom profiles for sensitivity and RGB lighting; as long as you are signed in to Razer’s Synapse software, you can set an unlimited number of profiles. You can also store up to five profiles in the onboard memory for use wherever you connect the V2. Once a profile is set up, you can easily switch between options without having to log into Synapse.
