Revised Rating: I am so pleased with the seller of this item that I had to go back and update my original rating! They read my review and immediately offered to either replace the first broken tire inflator or refund my money. I decided to get a replacement as it is such a useful product that can either be plugged into the wall and charged (wirelessly while in use) or plugged into your car's cigarette lighter socket while in use. Wish me good luck! – Initial review: I bought it in May 2021 and just tried to use it for the second time today. Unfortunately it doesn't work anymore. The digital PSI gauge was bouncing all over the place (29, 44, 66, 72) so it didn't actually start inflating my tire, it just shut itself off automatically. save your money
