For this price, the mouse is good and served its purpose. In stand-by on the mouse you have to order by clicking on a momentary wake up the mouse. Pure Move the mouse is not sufficient for this purpose.
In addition, the mouse has an On / Off switch.
The wheel is made of rubber and has good resistance that that one does not scroll up and down by mistake
Unfortunately, nothing like Logitech and Co. But otherwise everything tip top.
