What can I say. Based on all the positive reviews, I thought my experience with this tire inflator would be positive. Boy was I wrong. It never worked from the start. When I tried to use it, a lot of air leaked out somewhere behind the dial. I suppose you could assume I just got a lemon and my case was an isolated case, but that still doesn't make it right. I returned mine and got a refund instead. That's disappointing as the materials and overall design feel solid and not cheap. If you decide to buy this tire inflator, I hope you have better luck than me.
