I got this when I had a flat away from home and had forgotten to bring my patch kit and spare tire. I was near a Walmart and this was the only patch kit they had. I was not optimistic at all but was too stingy to buy new levers and a new tube so instead I bought this kit and re-used my punctured tube. And that actually worked extremely well. These patches are just like stickers, you simply roughen up the tube and then stick the patch on the puncture. I did not have a leak in that area of the tube again. Now I keep using this kit until I run out of patches. The levers are nothing special, if you want really nice levers get the Park tool ones in blue. But I cannot complain about the levers either, they are not broken yet. That other tool is very basic too but if you can get this set for cheap I can recommend it. And I ride my bikes a lot and have tried other patch kits.
