We purchased two of them (two cars), and LOVE the Airmoto. Had the opportunity to use it once... just a week after receiving them. Had a FLAT tire, after attending a late night basket-ball game. The Airmoto revived the tire, and we drove home, safely. Next day, had a long screw removed... and plugged the tire. We plan to buy 4 more as CHRISTMAS GIFTS. Definitely one of the BEST BUYS I've ever made. It's very portable (small), and EASY-TO-USE! You can't go wrong...investing in this Great...
