It sounds cool, but I'm weary of any auction that has that many mispellings.
Plus it doesn't have a plug, you have to spend $70 and cram bare wires into the diagnositc port.
I'd like to see screen shots of it before I made any purchases.
Look around, there is plenty of OBDII code readers and software out there. Don't jump on this one just because it says it's specifically for BMW's.
