Logitech Signature M650

For months I have been trying to figure out what the issues were when using this mouse. Trying to fix things, adjust setups etc. Then it dawned on me, maybe it is the mouse. Mine is fecal matter, my wife's one works fine, I have never herd her complain (hence the 2 stars) otherwise it would be just me leaving 1. Sometimes the mouse wont work when it is in use from the other side of the keyboard (via the bolt), forget 10 meters. I would not recommend this product ever, chances are you could be Okay, but why risk it.
