I'm a Ford technician and I repair and service cars and trucks. I bought this gauge for home use to check air pressure mainly on my Harley Davidson. The first gauge arrived and the end that attached to the valve stem was leaking. I was about to contact the company, but before I could do that, I received an email from owner and co-founder Frank Jackson asking if I received the sensor. I said yes and described the problem. I requested a new hose, but a few hours later, actually at 2am, I received an email saying he was sending out a new gauge. I received it in less than a day and it works great! Snaps onto hard-to-reach valve stem, inflate tires with one hand! More accurate than my "professional" gauge at work! Buy from this company and you will not regret it! Excellent customer service!
