Ultra compact mouse, convenient to move, it takes very little space. Its white color makes them less visible traces of fingers, a very good point. The quality and ingenuity Logitech await you. The service also. GP Alkaline battery is supplied, the battery compartment has a place to store the receiver, and of course under the mouse is the famous little on-off button, nothing extraordinary for a Logitech mouse, but yet so practice. 5 stars for this beautiful little mouse with an excellent value!
