After my third cheap, chinese, Ebay OBD comm device failed I got a little fed up. I have read others also have no end of trouble with these.
Just want to post up what I now have. It does cost alot more than the Ebay tat but after 2 months and just under 20 connects it hasn`t let me down.

I have the Kiwi 2 [bluetooth for android]
Took a few days to arrive and I was lucky with customs duty.
Connects to my Samsung Tablet and phone without problems, I`m running it with the Torque OBD Pro App.
Shameless plug I know but if your want a reliable device this is it.
