Luckily haven’t needed it yet.
Worked, holding at 30PSI
I have carried them for a year now, used my first one last weekend. I did not have high hopes for gluing a piece of rubber to the outside of a tire to work... but it does. Patched a tire on a guys machine we rode up on last weekend pretty deep in the woods. Filled it up to 5 PSI and it held.
Very efficient and courteous
I gut a slice in the side wall just below the tread on my back 28inch Wildthing Tire found gluetread pach and wow it works I Follow the instructions and I have not lost a psi in 2 months from that pach I check it every weekend with Soap and water looking for bubbles and nothing now I don't go out on the trail with out a gluetread kit it's a must
