This keyboard was terrific when I first started using it. I liked the touch and some of the special features (putting cmptr in sleep mode), and the heavy weight of the board. After using it for about a week, I went into my email and my email program started acting strange in a scary way. I closed it and went to a secure web page and tried to sign on about 20 times. The curser was not moving to where it should. I could not open this web page. I then noticed that I had about 20 Google homepage screens open. I cloosed them and then shut down and re-started the computer. I entered my computer password many many times over, and the computer would not accept it and I couldn't re-start it. I spent hours thinking about this, and when I fianly connected my OLD keyboard, everything worked just fine and all the problems were gone. This is not what I would call a friendly product. I tried to report this to someone at Amazon, but all I got was happy talk and no real concern or comprehension of the problem.
