I have one, and thought I wouldn't say it is fantastic, it basically does the job. Biggest flaw is lack of backlight (I wonder if you could just throw an small LED back there or something? I have no clue how you would wire that though) and as someone mentioned, keys are not the most responsive. Also, I sometimes have a double click issue happening with the left click, which can be very annoying. I think it has to do more with interference of the signal more than anything else, though.
