Logitech M570 Wireless Trackball – infuriatingly close to being a good device.
After decades of working with computer mice I have repetitive strain in my right wrist. It’s not too bad, but it means that if I use a traditional mouse my wrist quickly becomes very sore, with pain right up to my elbow.
I’ve found that using a thumb-operated trackball is much better and doesn’t generate any pain at all, but there are few of them around. I’ve been using the Logitech Wireless Trackball M570
The switches under the buttons wear out very quickly – I mean within 6 weeks of using it. The left button is now very twitchy. It often double, and triple-clicks when I’m trying to single click, and selecting text or doing drag and drop is just almost impossible.
I thought maybe I just had a bad one, so I bought another (from Amazon this time), and it worked great for the first few weeks, but now it has gone the same way.
Of course, being an eletronics engineer, I had a peep inside. The switches for the right and left buttons are the same, so I swapped them and the fault has gone away again, or at least it has moved to the right-click button, but I can live with that for now.
Problem is, I can’t actually find any other thumb operated trackballs.
