Full disclosure - this is the first trackball mouse I've used for quite a while (since the early 2000s), so I'm not exactly an enthusiast, but i wanted to share some thoughts on this thing after a few months of consistent daily use in an office environment.
Firstly for the money it's great. I paid about £42 for it and it's been a significant improvement for my postuerenif nothing else (and way better than my traditional mouse) Reading some reviews about it I was a little concerned about:
- The size - apparently some people found it too small
- The "skirt" of the mouse
- The feel of the silent mouse buttons
Size wise I've found it comfortable. I have average sized hands and my pinkie rests on the desk, though not to the detriment of using the mouse.
The "skirt" did take some getting used to, and I don't really think it adds much to the device - though it does stop the hand slipping (as it's a smooth plastic without rubberisation), so I understand it's purpose.
The mouse buttons feel great - no issues there.
As for my general experience - I've noticed that the ball does suffer a bit of stiction now and then but it's generally down to my own lackluster care for the ball and bearings. When clean it is actually pretty smooth and you can pretty accurately "flick" the cursor. The scroll wheel is a little slack on its axis which I don't live but it's hardly a deal breaker, but otherwise it's been a great little runner!
