- No need to move your wrist. More accurate than a mouse. Buttons are easier to press than mouse buttons. Easy to use with both hands. You can shift from the left side to the right without thinking about the wire. No mat needed. The ball is exceptionally pleasant to the touch, easy to pull out :) The battery compartment has a hidden niche for storing a small pimp sticking into usb.
- Overcharge. It takes a few days to get used to the touch wheel replacement. The trackball is too wide for a small female hand. Batteries need to be replaced. Ball stops need to be cleaned. Slightly aching fingers from unaccustomed. The battery compartment is difficult to open.
