High or Low DPI?
DPI measures the sensitivity. A higher number means that you can cover more screen space with only a slight movement of their wrist. 400-800 dpi is the standard. You may feel inconvenient to adopt the high dpi mouse at first，but it can protect your wrist and make reactions playing games faster.
