I bought this air blower for several reasons, firstly because I have five cars with air tires so it gets used a lot. In my opinion, using this type of inflator is easier than lugging around an air hose, pressure gauge, and stool. I am 71 years old so unnecessary kneeling and bending should be kept to a minimum. The manometer has a good magnifying glass, so the air pressure is easy to read and reproducible. The device is reliable, well made and made in America. Delivery was quick and the inflator was as advertised. I would recommend buying this product.
