I got this product for my car tire pump and it works great! Now it heats up a bit when the tire is very flat. According to the manufacturer, this is normal for this product. I feel a little safe to have this tire pump with me when I travel to different places. It's very easy to use and I love that it has a little lever to keep the air nozzle on the tire while in use. The built in big got function comes in handy when you need to use it all night. It comes with multiple connectors in case you need it for a bike tire or to blow air into a ball. This is a great product at an affordable price!
