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.

Got a hole in your tire? Get this kit. It works great.
This was purchased in a pinch, and it plugged the hole on the tire first try. it is still holding to this day.
