good patch

Very good

Great product and great customer service

Initially I thought these were self "vulcanizing" or self-adhesive, but I was wrong. You still need an outside agent to activate this and have it adhere to the rubber. Aside from that, the value and price of this box set is great. Got to finally use it and it worked really well.

good quality

These are really crammed in the box! Some are slightly bent, but not terribly. I'll just use them later so they have time to flatten out as I use the rest.I haven't tried these on a car or motorcycle, but they work well to seal a leaking inner tube on a kids bike.Since there is a small hole in the outer bike tire, I put a patch on the inside of that to prevent stones from getting in, but I rotated it so they two patches are offset. (Otherwise there would probably be a lump on the tire.)

I like that these patches have a split backing on the sticky side making it easy to pull the backing off. You get a lot of patches in the box (100 pieces). I used one last night to repair a nasty plugged repair in an ATV wheel. I always had leaks recurring. I finally pulled the tire off the rim and put one of these patches on using all purpose tire cement. So far, so good. It's nice to be able to do home repairs to keep equipment rolling!

These have a nice vulcanizing gum on the back making repairs nice and simple. I've only repaired one tire so far but it's holding up with no issues. They were easy to apply and holding up nicely so can't complain. Price was good.
