"Item arrived worked just long enough for me to throw the box out. Then the mouse decided not to work anymore. Then USB ports quit and keyboard and finally switching from PC to PC quit. I was bummed from the get go because this device also doesn't allow the computer screen to sleep when the PC does so every morning I find my screen flickering because its trying to shutdown. I contacted the seller after the fact and asked them what options I had as far as returning it and they never responded.Junk!"
