does the job when I'm standing/walking and sitting
I got this because I've taken to standing and walking on a treadmill when working, it works perfectly for me, didn't take much getting used to but then I'm used to using my thumb with the xbox controller, maybe if you haven't used one then it will be a learning curve, but its pretty easy.

Brilliant. This completely changed how I sit when I use the PC
I'm no longer sitting in the same position, always reaching forward. Now I'm controlling the mouse from any position that is comfortable - my posture has improved, my shoulder pain has eased, and using the PC (which I do for work for hours every day) feels much more natural. Getting pixel-perfect control of the cursor position is tricky, so it is no use for graphics work, but for general PC use it is great. I wish I'd found this years ago, and I'm about to order another for my partner.

Not a great generic product
Not a great generic product made in China and sold to many resellers. Cheaply made and mine gives regular problems. It works up to a point, but it's not a smooth running mouse.

Helps reduce RSI and stops it gettings even worse.
Helps reduce RSI and stops it gettings even worse. Takes practice to get used to but thank goodness for it's ergonomic design and that makes it ambidextrous for both left and right handed peoople.
