Query: Disappointed

Upon receipt of the tire gauge I was pleased with the large display and size of the item. When I applied the gauge to a valve stem it wouldn't seal and air continued to leak out. I applied it to three of my other vehicle valve stems and the same leakage occurred. I returned the gauge for a refund. Note: By the way, the Amazon return process is no hassel. The Amazon representative provided me excellent service.
