Very good product, this is almost six months I was this time or I post this comment and I still have not changed the batteries provided with, otherwise the mouse is ergonomic and very precise, I had the opportunity to test it on several games including Battlefield 3 FPS triple A, and to my surprise, the mice also seemed a usb accurate at the very good game! the receiver is high-quality Logitech! However the design of the mouse remains a goodbye because even if the product is very simple, one would expect better while maintaining his sobriety! The mouse has two buttons on the left side is used for Back Front / Rear on the Web or programmable game or windows with software such as KeyRemapper, above, a small button to "unlock" the mouse to q ' scrolls quickly. A good product! :)
