Beautiful thing, Standard Design. The design itself is also often used by many larger and more well-known brands. The mouse is really good for the price. Unfortunately, my right thumb often comes on the side button, so I suddenly knife or one page Jump - annoying. Much worse is the "Lift" function. I was naive and thought there was some kind of chip and a device which, in my case the Mousepad measure the lower surface, and then align the three lasers. Nope! This looks more like a rough gear on the button, the laser part way down / moves with every click above. Total nonsense and solves only out of frustration! If you press the button by mistake, you have 10 minutes to try out all the zillion versions, until finally the initial situation is restored. Except for these two flaws is a good product!
