I unpacked the Mouse, installed and running without problems. Have the Mouse connected to a Fujitsu Siemens laptop that has Bluetooth and exactly for this purpose this Mouse is optimal. The size of the Mouse's fine, it's just a Notebook Mouse. But it fits comfortably in your hand. The buttons are good and the scroll wheel fulfills more than its purpose. Personally, I find it very good that the Mouse is functional and not ausgetattet with too much frills.
Delays as partially read in other reviews, I could not tell. I think that then located on the computer and not on the Mouse.
I also like the small pocket / bag. So that the Mouse can be packaged well stowed in the notebook case. The only shortcoming is that the mouse looks dingy quickly because of their smooth surface. For that I have to deduct no star, after all, is not the Mouse be chic, but fulfill their function. She does great.
