Love it! Small but not too small, works well on all surfaces I tried it on.

This is the second Logitech mouse I've owned now and I love them. Never an issue and the last one I had lasted over 3 years. The mouse is a nice small size, perfect for my laptop and works great on all surfaces.

Used with Macbook Air once the Logitech utility was installed. It works really well. The desk in my office have glass tops and it means I no longer need a mouse pad. The oversensitive wheel can be an issue during presentations as the slide being displayed can change when you don't want it to.
