[This review was collected as part of a promotion.] I like the low profile of this mouse. It feels better (ergonomically speaking) to use. It seems easier on my wrist than the curved or arched-styled mice. The clicking seems solid & center wheel works well. Came with batteries included. Quite stylish and glossy. Easy plug 'n play, the usb dongle is small and doesn't get in the way. I've been using it just over a week on my new Envy 17 and am satisfied with my purchase (so far).
