I would now presumably to buy a wireless mouse and a separate USB Bluetooth Dongle and not a combination device. Because one here but spends quite a lot of money just to have a Bluetooth mouse and having no wireless mouse ...
No matter: the processing of the mouse is very good, they leigt great in your hand, you can also reach the modifier keys very well. The battery life is in my eyes very well and by the charging station you always have everything in the right place.
The only drawback is the quite high weight of the mouse. Because you have to get used to, but that you have to set a mass in motion here.
By and large, but highly recommended
