Very nice and good product. I was looking for a mouse for PC as beautiful and practical as Apple Magic Moss (I already own with an I mac) and I found it at Logitech which for me is one of the references in the world of the accessory IT. Automatic installation with my laptop Asus. Nothing to do. In addition I enjoy the coupling with 2 different computers without changing the settings for each position change. It very small with a very soft almost velvety, with no ugly useless button, very fine to be put in the bag of the laptop, see the pocket. Even if the small cable for recharging is under the mouse at least one branch nothing, which seems a bit incongruous, we appreciate the ultra-fast charging. So great product that I recommend for multimedia use, when you do not want to lose a USB port on his laptop (important!) And that is a fan of slim formats. And congratulations for aesthetics.
