This product is great to have around in your car. This makes it easier for solving the problem of a flat tire. I mean! In my case! I rather use this method first instead of having to remove the tire and having to go through the spare tire dilema. For a temporary solution,this kit is perfect. And in some cases! It can serve as a permanent solution. This kit is great to have in your trunk. 👍🏻👍🏻👍🏻

Gets the job done.

Got 2 flats at the same time in freezing cold weather. Jack failed, but this product didn't.
