The Kensington Trackball Expert Mouse feels very comfortable in my hand and is easy on the wrist. It's perfect for long gaming sessions.

I was a bit skeptical about the sensitivity of this trackball at first, but it's just right for me. It's not too sensitive, but still responds well to movement.

I've been using this trackball for a few weeks now and the optical performance is excellent. It's very accurate and smooth.

I've been using this trackball for several months now and it still looks and feels like new. The build quality is excellent.

Considering the price and features, I think this trackball is a great value. It's a bit more expensive than some other options, but it's worth it.
