    Fantastic seller. Ordered item and when it arrived saw that it would not work on my vehicle. No questions asked just sent a return table and I sent item back. I got a refund few days later.

    Whole I mistakenly ordered this for my suburban it is for a Tahoe and by time I realized it, it has already shipped. The seller was great to work with and I was able to return it. I did not open the package because I knew it would not work for me and I needed to send it back. But the seller was great and it was easy to send back.
