Well made heavy duty tire inflator. You can feel the difference between this and a cheap fake port freight. Easy to read and has a nice no trigger inflation feature. Made of good material and workmanship. I bought this because my kids broke all the other inflation sensors by falling, stepping on, running over inflatable bikes, balls, or swim toys. This one looks pretty indestructible, and for about $10 more, it's nice to support a US-made product.
