Well, actually, I bought 2, and haven't used them yet. They're fully charged, and I thought by now I'd see someone in need😃
My dash light went on showing low air on a tire, however I was due for a service, and they took care of it on the rotation.
But I'm anxious to try either of them....soon😉🤜🏼🤛🏼 they are great to have with us on trips!!!
