Buttons are easy to push.


Outstanding. You can switch between your 3 devices, and you can also use it simultaneously with two computer

The scroll-ring is terrific -- the other trackballs I've owned (and there were many) had poor mouse-wheel substitutes or none at all, but this scroll ring actually works BETTER than a mouse-wheel. Simple, sturdy design, and a good-sized ball that tracks well and rarely needs cleaning -- great for using in bed. KVM-friendly, and plug-n-play on XP/Vista/7.



Good range, 15 to 20 feet

Comme dans le bon vieux temps ! Ajout de la souris sur Bluetooth et elle fonctionne comme un charme depuis ce temps (1 mois). Bon achat.

Battery Included Quiet Fast Response Wireless Excellent Build Quality


What is there to say It is a basic mouse.


Comfortable for a smaller hand. Can be switched off to conserve battery life.

- Good weight and table-grip keeps unit in place - Adjustable grip angles great for fatigue -Rechargeable, internal battery -Accurate ball tracking

My 7-year-old son loves it. It fits in his hand better than a full-size mouse, and the bluetooth works better with his old Mac than the usual Logitech USB dongle (with USB-C adapter).
