I've been using these pumps for years and the last one finally died. It used to cost $10. I recently got myself a pump starter. I tried to inflate a ten pound car tire but the pump failed. I liked the look of this tire and its performance looked good. I filled 2 tires at 10lbs each and 2 others at 7lbs. A little warmed up, but went great. I love the auto shut off and after checking the pressure with a pressure gauge it seems accurate. Also, I've worked in tight spaces, so the clip-on attachment was great. I highly recommend it.
