Bests & Worsts Reviews from Amazon

It works just like the directions on the product description say. I used it to fill my car tires to between 43-44 PSI. My first tire inflator didn't have a gauge on it, so this came in handy. I double checked the accuracy by using two other tire pressure gauge I had lying around. They were all about the same. The second tire inflator I bought (first one took forever and was really loud), had a built-in analog gauge, which I thought was going to make this digital gauge obsolete, but good thing I had it because the analog one was way off. I uploaded a picture of all the gauges. I definitely prefer the digital one.
