Good handling, at a great price

It was clear for me that I want to have a mouse that works via radio, and 2 additional keys available.
I have been accustomed Button 4 on the left and 5 button on the right side of the mouse. According to the browser back and forth.
Now here are the buttons both on one side, but also because you get used to, even if the order ME other way around (4 and 5 reversed) logically appear. As I said, you can indeed get used to everything.

The mouse fits comfortably in your hand and even if I have not yet had to change the DPI resolution, I have found that it works very well, even on the table without a mouse pad. The battery I had not change, let's see if the life really as high as indicated previously. It is also interesting that you do not under the mouse - can see the LED light up - as usual.
