I just got this keyboard in the mail and i love it! I am using it right now to type this post. I will not say that it is perfect, but it's good enough for my needs. If you would like to buy it and try it for yourself, go to amazon.com and dearch for "Rii bluetooth keyboard". to sum up my 2 hour experience with it so far, I separated,the pro's and the con's.
incredibly fast shipping
awkward to type with touchpad in the way.
takes multiple swipes,for a 180 turn in openarena
must keep line of sight between connector and keyboard.
Despite all the cons, I really like this keyboard. I just used it with my raspberry pi to play minecraft and openarena. I love this and highly recommend that you buy one too. Have Fun!
