This is a great HTPC keyboard. Compact and has great range (I can use it from all the way across my house through several walls and it still works fine, not that it's terribly useful since I can't see the tv
). I shut it off when I'm not using it and the batteries are still going strong over a year after I got it.
I wouldn't want to use it as a main keyboard where I would be doing a lot of typing, but then I'm a bit of a keyboard snob so it might be fine for most people.
