I haven’t used this yet, but I bought a case to give to my family members. My friend who came outside to a flat tire. It was a Sunday in Utah so there was really no one that could fix it. Walmart told her to get this product. She had to drive home immediately following using this product (300 miles) It has been over two months now and my niece is still driving on that tire. It was a brand new tire that was costly so she decided to just wait and see how long this product will work. Great gift for anyone in the family that drives. This does not work on a blown tire. If you wake up in the morning and your tire is flat, or you get out of class and your tire is flat, just use this product and no calls need to be made.

Great mini-compressor at a great price.

I bought this little guy to inflate tires on my two bikes. It works perfectly. I especially like the set-it & forget-it design. Simply hook it to your valve stem. Once on the stem, it generates a digital reading of your current PSI. Then enter the desired pressure, press start and it starts pressurizing and counts up as they're inflating. Once the target is reached, it shuts-off automatically. What could be easier. BUY IT!

It's good to have it when you need it, rather than need it and don't have it!

Works really well. Great for topping off air pressure. Why spend $3.00 for a couple of PSI's. Good addition to my automotive emergency kit. Quick, easy to use and noise level is minimal.
