The one that came with my PC. I just looked at the back, and it (imagine that) says KeyBoard. It works fine for me, a bit loud but otherwise ok. I also have a Genius keyboard on the other computer, can't remember the model, but it's the cheapest one there is. Works fine, a bit quieter, softer, and, on the overall, more comfortable than this one, but , unlike it, it has no additional buttons. Not too much of a drawback, though, as I only use volume controls, and my mom pressed sleep last time she was cleaning the keyboard (she was doing that while the PC was on ).
