For the past 12+ years, I have been using the corded Optical Trackball that Microsoft made and then discontinued. Seems like everything they make that has a proven track record gets discontinued with them (Win98, XP, Win7, etc)! I couldn't find anything that had the same configuration until now!

This is the best Trackball mouse on the market for both PC and Mac

This is an excellent product. It is very useful if you are using a laptop whilst sat on a settee because you can use it on the arm of the settee when a standard mouse needs a flat area to work properly. It works well with games or just navigating around. I would recommend to everyone.

Reliability

I've always preferred trackballs over mice and trackpads, but they've become difficult to find. I needed a new one for a MacBook Air and wanted to try a wireless trackball, even though I was nervous about jittery control and short battery life I've seen in older wireless trackballs.

I've been using Logitech's Track Ball since before it went "wireless"; well over 10 years. I went wireless with the Model M570 several years ago. I have one for each of my five PCs but needed another for my Chromebook.

I've had the wired version before this which came in handy when I had a wrist injury. I now use this wireless version when outputting my PC to the television. Great mouse, great standard features.

Excellent! I could never go back to a normal mouse after using this trackball. Several people at work have bought them after trying mine and are also well & truly converted! Build quality is superb and delivery from Novatech was super-fast, as always.

Sure anyone new to it always wonders what it is or how to use it, but I absolutely love it! once you get used to it having your hand stationary, and having it be so reliable is fantastic. downside. you have to clean the guides occasionally as they get dirty.

A well-rounded trackball for laptop and desktop users alike.
