I bought a set of TRQ brakes and rotors for my 2016 Mazda CX-5 from 1aauto. Everything looked good on receipt so I installed them following a good 1aauto video. Within driving 200 miles I noticed my gas mileage was deteriorating. When I took off the brake pads I found that they had 'chunks' missing. As I need this car I went to local car parts store and bought new brake pads. After installation mileage was restored. I contacted 1aauto and was told they would not refund my purchase as I had installed the brake pads. Having no confidence in their parts I wouldn't have wanted their parts nor would I have been able to wait to ship the defective pads back, have 1aauto inspect them, and then ship me replacements. Maybe local auto parts stores cost a little more but they would have replaced their lifetime warranty brake pads on the spot.
