Our Verdict
J-Tech Digital V628X
Razer DeathAdder V2
The J-Tech Digital V628X and the Razer DeathAdder V2 are two very differently designed mice. While the J-Tech has a unique vertical shape designed for extended office use, the Razer has a more standard, straight-forward shape designed for FPS gaming. Overall, the Razer performs much better, but users looking for a unique vertical design will likely be more interested in the J-Tech.
