But now to the Gigabyte Mouse:
+ Haptics: The materials are pleasant to touch and high quality. Only the scroll wheel has a little loose, but after a nice defined detent
+ Ergonomics: The mouse fits comfortably in your hand or fingers (normal laptop mouse size), the additional up / down buttons are well placed
+ On / Off slide switch on the bottom to turn off the mouse when it is not used or transport
+ Installation: Runs without installation of additional software; Easy pairing with Bluetooth dongle (mumbi Mini Bluetooth Dongle USB Adapter Class2 V2.0 EDR 100m - Windows 7 / XP / Vista / 2000)
+ Price: Much cheaper than comparable Logitech products. And it's not as if Gigabyte had no brand.
Clear recommendation to buy this mouse!
