I bought window tinting for my husband several years ago and it was fine so we bought a bed cover from them last year they installed it and it started falling apart we asked them before the year warranty was up and they told us it was our issue to go to the company who sold it to them. We called the company they said no quality bumper is responsible for the install we called QB again they still won't help us so now we have a truck bed cover that is falling apart cant protect our tools etc...this was almost 2000k this company does not back their work
