Customer Reviews

Best track I Have used, this my second One
This makes the 2nd one I have bought, I have tried many and this the greatest I have found.

Good, until I dropped it once
Had a little trouble getting used to doing the ball with my fingers instead of my thumb but the brain adjusted and I tolerated a little pain - much less than the RSI from a regular mouse. But then I dropped it once. Gone.

Big and Clunky
Unless you have very large hands, you might find this device hard to use as the device itself is large and the buttons/scroll are too spread out. Other than that, the device works well--no signal drops and saves space compared to a mouse.
