Logitech Trackman Wheel Trackball Mouse

I'd disagree with the last review, i used it for gaming and after using it for a while found i could perfectly move the mouse instantly to where i wanted to click. after time tho the ball loosens and its difficult to do it and after it while it stopped working. plus i dont think it is worth the money

My hubby has had one of these mice for over 12 years and it has only just given up the ghost!
I have no worries about buying another one, cos I know I've got at least another 12 years before it needs replacing again..
This mouse is perfect for those who have to spend extended periods of time working at a PC, as it helps to prevent RSI, so if that is a consideration, don't hesitate and buy yourself a trackball mouse.

ive had myn for a few years now and never had a problem with it, gotta clean it every now and then but with any physical mouse thats the same, very reliable, very comfortable, but not particularly good for gaming as its difficult being very accurate with your thumb and when moving very fast the ball looses track and ghosts, other than that very good

One of the best designs. I've used it for many years. 2 buttons + wheel (which includes third button). It may not have 254125 buttons, but this means you don't press them by mistake. Unfortunately, on mine, the right button presses itself randomly. Compared to newer models from other brands it lacks only laser and horizontal scroll (like tilt-wheel).
If it was reliable, it would have got 5-stars (considering age) or 4 (when compared to newer technology).
No matter how hard I think, cannot find any other faults.
Shame there is nothing on the market that fixes reliability and features concerns at any reasonable price.
