Excellent quality and as advertized.
Size: 58pcs
It's a bit over packed and hard to close once opened. Too much extra stuff in the kit. W. O. B.

Works awesome. If you don’t use them within a year replace them. It’s way cheaper than a tow truck!

Bad Product

There was no pressure in the can. It would not even inflate a bicycle tire. Be careful there is no amazon refund or return with this item!
