The J-Tech Digital V628X is a decently comfortable mouse. The side buttons are a bit too low to reach comfortably, and the scroll wheel is more comfortable to use with your thumb but feels much more stable when using your index finger. On the upside, its vertical design should reduce strain on your wrist if you use your mouse all day, though we don’t currently test this. While it has an adjustment to change the angle of the mouse, unfortunately, it doesn’t hold well so even when it’s tightened, the angle still moves a bit, making this feature less useful than it could be.
