used these ever since they first came out, way back in time, they are great to use if you have RSI or other mobility wrist problems, well worth the money and a great product

Okay, but not as good as the old Microsoft trackball it replaces. Too narrow so that the buttons on the right don’t fall naturally to hand. I’m getting the hang of it slowly, but a scroll wheel would be useful. Looks better than it feels or works in practice.

It is so easy to use .much better than a normal mouse all you need is thumb and finger .no waving your arm about .no more aching wrist it fits nicely when you just lay your hand on it .its faster than a normal mouse so great for games too

This is perfect for a desk with limited space, or on a ship or boat that rocks. It stays in place and is comfortable to use. Simple plug and play. I needed this for a computer upgrade and KVM switch that would only accept USB rather the old PS2. Worked first time with windows 10 and XP with no drivers needed for installing. Nice smooth action and accurate.

The ball doesn’t roll as freely as I would have expected so I tried smearing some wd40 on the surface after checking if there was dust which there was not. It has become slightly better over the last couple of weeks or it could be that I have become used to it. Great though if your limited on space for an optical mouse.
