I bought this PowerShot 4,200 4 gpm & when it arrived I picked it up at the ups station got it home and it had a dent in the gas tank. I called Tyler tool and told them what happened in the shipment and send him a picture and then they gave me $85 credit to buy new tank and strainer that was missing and so everything is really good. This pressure washer is the bomb.
