i just bought a pack for the first time last weekend.
my hose had a gnarly gash in it.
i put on 1 strip ( its essentially rubber with a strong adhesive) and the adhesive actually stayed strong, unfortunately the pressure of the water burst immediately through the thickness of the rubber.
so i went back and used the rest of the pack and just kept wrapping the hole, gave it 3 or 4 layers or something. this time around the thickness of the rubber contained the water pressure! yay! but the water pressure decided to bust through the adhesive portions now.....
i will admit, my wrap job wasn't perfect, nor did i leave the newly placed adhesive patches for 24 hours before turning on the hose, which is recommended in certain cases on the package, but still, my problem exists anyways...
i would give it 2 out of 5 stars. im sure it works great for a lot of applications ( wrapping a hose was one of them i thought), but it failed for me mostly due to user error most likely, but unsure....
