Range is excellent
How poor is the range?
This is a very nice and well thought out keyboard. Since it is from Logitech, the build quality is fantastic. The size and feel is similar to a laptop keyboard and that (for me) is a good thing. The track pad is multi-touch  so you can use two fingers to scroll and pinch to zoom in supported applications. It doesn't have a crazy amount of useless buttons on the top like most multimedia keyboards. By far the best thing about this keyboard is the form factor. It's small, light weight, has smooth lines and will feel just as comfortable on your lap as it will on your desk. There is also a convenient on/off switch located along the top edge, so if you want to throw it under the couch and forget about it until you need to see who that actress in that one show is, the batteries will still be good. Range is excellent, Basically if you can see the words you are typing on the screen, you will be able to type them. No missed keystrokes so far.Con: It is not back-lit, but it never claimed to be and neither is the Kindle.Bottom line: It's well made, inexpensive and works great!
