My husband just loves these patches, he uses them on all type of tubes if it's a small leak. Great for bike tubed. Saves us money on the grandkids bikes.
These patches are a piece of crap. The tube surface has to be very clean and scuffed for it to barely stick. It works for about 1-2 hours and then comes off, wandering in the tire, eventually uncovering the puncture. Don’t waste your time with these.
I like that these patches are glueless. No mess no fuss. Find the hole apply the patch and re inflate. Bam! Good to go!
