Sorry , someone can tell me which of the SBB, zed-bull, Ad900(I speak of Clon*) is able to read the most? the transponder? L?SBB works via OBD, and the cars without OBD? With adapters, Car type, the ones that I have already? the CDP+ work?

According to the descriptions of the products, I saw the Mercedes, and BMW.

It would be nice that someone who has already? the product, write something in question.
What a bad luck ,almost everything, or ? in English, or in chinese, partly in English:-(
