Really one of the finest produce I have ever used. It had done every job required well as in the description. My tire was completely flat & in less than 2 minutes it was filled to the correct capacity. The gauge helped tell me the level so I wouldn't over-inflate it. Very powerful and fills tires quickly. It also worked well with the basketball and bicycles. Even better with a canvas bag, very handy. I recommend to all auto and small truck owners. It has made my day easier.
