The first device I purchased was defective, so I needed to return it. After contacting customer service, I received an extremely prompt response, and I have now received my new device, which works perfectly with no issues.
I received great help with the software installation. Many thanks to the customer service team.
I easily found the tool suitable for my 2008 Cadillac, and the ordering process was very straightforward. The goods were also delivered exactly as promised.
