bought this for my father who was sick of dragging a cord around. says he likes it , fits his smaller sized hand well. installation could not have been easier.


Great product!!!

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.

Pros: Good size, it actually comfortably fit an adults hand You can feel the wheel click by click The wheel is a good size and grips your finger well Tracks well on every surface I have use it on


What is there to say It is a basic mouse.


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

-The M575 and its predecessors have been my gp-to for years, hands down the best mouse on the market for the money. Accurate and lightweight, they'll last a number of years if given decent care (I recommend one of the custom-fit zipper cases). - They shipped it so doggone fast that it arrived two days early! Now THAT is impressive!

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).
