As said in the title, this mouse is a very good mouse, laser comfort is really good (the pointer does not jump, track relative to the movement is good) It's been just a week that I have, and it replaced my wireless mouse 5000 Microsoft Wireless 5 buttons! (Try it and adopt it! ^^) That said, careful not to believe (as I do) that these things on the mouse buttons are length, this is not the case! C'st March 1 classic buttons (right click, left and center), but it is a laser, and it is there that makes the difference! 5 stars for + than excellent price / quality (12 !!)
