Amazing product.
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.

Seems fine
The kit looks good to me. Better than my old one that lasted 15 years.

Would buy again
No issues with this product. The oversized T handles make it a bit easier to complete the plugs. Definitely easier for those who have trouble gripping smaller items to work with or for those with larger hands. Valve stem remover was nice quality and nice to have additional valve stems. Would buy again. Wish it had a better case but I can't complain for the price.
