Pros: precise, and is great for limited space I even use it for some CAD work I own 2, picked one up when my Microsoft Trackball Explorer failed a 3 foot drop test

Cons: Newegg is currently out of stock, I wanted one for my new laptop

Overall Review: 1000x better than a regular mouse

Pros: cheap

Cons: supposed to be 2 gig, only fits 1 gig

Overall Review: only out 6 bucks (side note) I will never use DHL shipping again

Pros: Setup was very easy.

Cons: None so far. Only had it a few days.

Overall Review: Not a gamer, but like a fast machine. Replacing a ten-year-old Win 7 machine that had an FX4 processor. It got tired and was time for something new. Not a fan of Win 11, but it is what it is. Had to create a Microsoft account just to get it started and found a way around the log on when starting up. Most likely won't mess with any performance tweeks. Hope I can get 10 years out of it.

Pros: Cheap, does what is advertised to do.

Cons: none

Pros: did a nice job, until it died

Cons: lasted 2 weeks - bought it somewhere other than Newegg

Pros: simple and works, reasonably priced

Cons: haven't found any yet (month and half of daily use)

Overall Review: I have been using trackballs for years, and I really like the scroll ring, thought I would hate it. Not quite as nice as the Trackball Explorer I had for years, but it isn't ridiculously priced like the Explorer was
