The mouse has a sophisticated, a bit small for me but perfectly suitable. I have a mouse by Microsoft and the looks in comparison to Gigabyte M7700B Compact ziehmlich plain and clunky. Gigabyte M7700B Compact is ergonomically very nicely shaped, the buttons work well and are relatively comfortable. The color is shiny satin top and sides and rubberized. The installation went smoothly (Windows 7 Home), the mouse was recognized equal, then I tried a few things in Bluetooth settings, so that the connection with the mouse works better (at the beginning after the new start I had the mouse again every time login, I have a Dell laptop) and now everything runs smoothly. What's important to me that the mouse works without Mausepads, and it does no questions asked (on sofa, desk etc.). Strong buy recommendation: Function, Ergonomy, appearance and price of course everything fits together perfectly Gigabyte M7700B Compact Bluetooth Laptop Laser Mouse, Wireless, Bluetooth black!
Addendum on 10/11/2012: After a year in use I can only confirm again: good mouse works without A ny problems, is recognized equal to the laptop. The only drawback: is mouse komplekt off, so with the button in order to save batteries, is no longer recognized and must be reinstalled. Therefore, I never do from the mouse. For batteries last troztdem relatively long!
