I bought one of these keyboards years ago, and it worked great! We used it for our media player for years and never really had a problem. Sadly it was lost, so i began my quest to purchase a replacement. I purchased four from Amazon, and one directly from Rii. They all appeard to be knockoffs with very short range and random clicking of the mouse and glitching the pointer all over the screen. This remote is very different. The range is great, the mouse pointer is pretty accurate and it just works. The keys and switches feel substantial, much like the original Rii. The keys on the knockoff keyboards always felt mushy and cheap to me. I like the new left mouse button on this keyboard, but the new page up and down buttons are placed poorly. You end up clicking page up or down while operating the mouse pad. I wish the led lights were red like the original Rii, the blue is very painful on the eyes in the dark. Overall I am pleased with this keyboard offered by Vilros, and it is cheaper than other sites as well. I will definitely be recommending these to my friends.
