Update July 2019: My first one broke after about a year and a half. I bought another one to replace and will try again. That's great! I keep it in my car to inflate my bike tires before I ride. I had to buy a $1.50 bike stem adapter at a bike shop. I had a problem with the first one falling apart in the company, they immediately sent me a new one. Excellent customer service! I am buying another one for my husband to keep on his car. He borrowed mine for car tires and loved it!
