Review on EIGIIS Ergonomic Trackball Handheld Wireless by Kyle Miller

Compact and portable is often an advantage, but in this case it's a disadvantage. --- View photos. The device is too small to hold comfortably. The position of the trigger causes my hand/arm to feel uncomfortable after just a few minutes of use. -- Mouse buttons cannot be reassigned -- Ergonomically, the position of the mouse button is even worse. -- The shape/curvature of the mouse does not change. correspond to the hand. Smaller hands should also compensate for the position of the trackball (middle too far forward). I'd point out that I rarely complain about small details, but awkward/poor button placement is just an annoyance that can't be overlooked. The actual trackball reacts otherwise. If you want to try this mouse or have small hands, I can at least say that this is the best of the three wearable trackballs. Others have loose trackball bodies that make it impossible to use a handheld device (the ball won't stay in place). If you want to simulate an example of how this would feel in your hands, do the following: - Place your hand on a flat surface. - Without moving your THUMB, raise your hand and curl your fingers like you're holding a gun trigger (sorry for the crude example). See eg picture. Move your index finger and thumb and see if you can get that comfortable for as long as it takes.
