I bought this mouse to my K360 keyboard. Main reasons were 1. a mouse in Normalgroesse (not a small notebook mouse) and 2. the most important functions when surfing the Internet, they should dominate and 3. can unite about Unifying with my keyboard. In addition, there was the M705 in question. This I concluded but quickly, because the better M510 lies in the hand and the most important keys for me were forward / back arranged ergonomically better. These keys are to achieve bigger and better with the M510. The M705 is overcharging me personally with functions. But that must naturally decide everyone himself. About the Unifying software I was able to combine the mouse with my keyboard, so only 1 USB port must be assigned. It works perfectly in the usual Logitech quality. Battery life is long and the mouse also has an off switch to make them even to extend. So if a large cordless mouse with the essential functions needed that also is Unifying-compatible I can only recommend this mouse.
