I just got mine in the mail today and so far it's been pretty solid. Box advertises 33 feet of range but I only need it for 8-10 feet of range. It feels comfortable in the hands and to use the mouse is not that big of a deal, rather easy on the hands.
I got it for CHristmas... gets 20 feet of range. Super easy to use. A 25 foot HDMI cable and one of these is great!
