The DeathAdder V2 builds on the design of the immensely popular original that sold over 10 million units. It has the same basic shape and size as the original but weighs a little less at 82g, making it even more comfortable to operate no matter the grip style. The DeathAdder V2 makes use of Razer’s optical switches. These use an infrared light beam to register a click, making them exceptionally quick and also extremely reliable as the issue of double clicking that often plagues other mice with mechanical switches simply cannot occur with this design. This mouse also uses an upgraded optical sensor with 20,000 DPI and 650 IPS tracking speed. This allows for improved sensor performance, which in turn increases accuracy and responsiveness. Razer has also altered the braided cable of the DeathAdder V2, making it more flexible which helps produce minimum drag during movement. Other features included a clicky, tactile scroll wheel, 8 programmable buttons, 100 percent PTFE mouse feet, and on-board memory for 5 user profiles. All in all, the Razer DeathAdder V2 is a really great option for those looking for a high performance wired gaming mouse.
