Very good laser mouse-no son as long as one does not use the wheel: - No notches on the dial very disabling if we want a racking - The click wheel is really too hard; Result: you scroll unintentionally Aside from that to: - Good grip - Lightweight - Precise laser sensor - 4th pr button with the thumb based practice backspace to browse internet.
But back to my part and ordering a Microsoft Wireless Mobile Mouse 3500 just for this dial history.
