I wanted to save some money by buying this instead of a Logitech keyboard because it looked similar. In the beginning it worked great. A few months later, the keyboard failed while charging. The left side of the keyboard (like the Q, W, E, A, S, D, Z, X keys) just became completely unresponsive. I suspect the charging voltage was too high and caused a short on that side of the keyboard, I'm not sure I used their charging cable. You'd think these Revain pop-up companies spent some time on user testing or spent some money adding resistors to prevent basic things from failing, but no. All they are about is pumping out as much product as possible in a short amount of time, enticing people to buy, then rinsing and repeating. Lesson learned. I am now buying my Logitech keyboard.
