Processing is super. The price is a bit high, but somehow Logitech usual. The mouse fits comfortably in your hand, very "handy". I have a relatively small hands and come to all buttons ran very well. The batteries will last very long. I had not expected. So with daily use of 2-3 hours to get quite a few months back in order. A little wear can be seen only on the pads under the mouse. But that's normal. Can I hesitate to recommend.
