At first this was great, worked for two years. Easy to setup and came with batteries. Has lot of perks of music buttons and favorites button right on keyboard. However, it started getting very weird on me all of a sudden. Certain keys stopped working or would keep writing when I was typing. Huge delay. I replaced the batteries and still same issue. I opened up the keyboard...very easy except there is one screw under sticker that says do not open (not sure why) because you need to take that one off to remove the cover. I cleaned the keys and it started working again for a little bit...then same issue after a month, but different keys. I gave up on this one now...going for a USB keyboard.
