So I bought it at a discount store for $10 first. I've been using it for at least six months now and never had a problem. He's aired several mower tires and tons of floats. No, this is not an industrial air compressor. It is not intended for these applications. As long as you follow the deadlines specified by the manufacturer in the user manual, you shouldn't have any problems. It comes with several different air fittings, which is nice. I leave it in my truck and it often comes in handy. So don't shy away from this product based on the reviews, I guarantee you will leave the device running for too long.
