I have used track-balls almost from the start of mousing. I hate real mice. There was one mechanical ball, early on, that worked really well, and is still produced, but the price is ridiculous.

Very smooth ball operation, no doubt due to its optical coupling; (No axles or wheels to deal with.

I would recommend this as a simple trackball that works well and is easy to use.

Ergonomic trackball that's easy to use

Wrist rest pops off pretty easily

This is an excellent trackball for first-time trackball users that would like to transition from using a mouse. The doctor recommended a trackball to alleviate my wrist pain, and I settled on this Orbit trackball after trying the older Orbit without the scroll ring.

No software included in the box
