I would like to leave a review because it is the first time I'm so disappointed for a product. I had a mouse before microsft blue track, a little more expensive. Side design, white version, very nice product, remains to be seen over time whether it will remain pristine matt white or marked traces forever. Listed ergonomics, I prefer to use the laptop mouse, smaller. But it really a far too narrow grip, we really wonder where to put her ring. This is the first time I hurt quickly using a mouse. The side of the mouse where the thumb rests creaks, there is a game in plastic and it squeaks each move. Listed sensor accuracy and RF link, nothing to say, perfect. But the mouse is not very accurate in the sense that its weight is distributed in the bottom of the mouse: When I move the mouse, the top starts moving and then caught the bottom which slightly changes the trajectory. Last thing, the click compared to my old mouse two, is harder (maybe over time), and very noisy, impossible to surf quietly in a telephone conversation drags on. In short, if it again ...
