Performs exactly as I had hoped. Much preferred over wired model. I frankly cannot understand why other people prefer a wired one. Particularly appreciate the on/off switch and the charging through the dongle. Fits my hand, actually both hands equally well. Reassigning some of the button functions made the comfort even greater .
