I am very satisfied with my purchase of the OBD2 adapter, This is by far the best OBD2 adapter I've come across. Fast shipping and the seller was so kind and patient in helping me get it running. Highly recommend this product! Response speed was fast, handling more than 2000CAN messages without a hitch, and I have yet to encounter any errors or bugs during my usage so far. I would highly recommend this product for anyone struggling with an OBD2 issue.
