After a few minutes without using it the left & right clicks no longer work.
However, the knob and other buttons work.
When it does work, I am very happy with it because it relieves the strain on my carpal tunnel (I had surgery on my right hand a few years ago)
Disabling the click wastes a lot of my time: uninstalling and reinstalling the mouse, even rebooting the computer.
I had no problem with the Urban Factory brand.
In hindsight I would use this brand again and not your product.
