Dear friends, what are the main differences between this model and model obdii protocol detector & break out box diagnosed obd obd2 connector | warran

Just looked at the obdII protocol detector & breakout box. Looks like the two are basically the same thing. I would say the otc piece is probably a little better quality piece, of course it costs a little more money. But the two will function pretty much the same way.
