it's not going to break the bank, but it won't hold the 110 pounds of pressure either, especially over a bump. I tried using some of those patches and stopped after half a pack because they just would not hold. I pump up to 110 psi and then bounce the wheel on the ground, and sure enough every single time i hear a loud pffshhhhh as all the air is removed from the tube. I went back to the classic orange and black patches with the vulcanizing glue. I tough the patch up, put liberal amounts of glue on an area twice the size of the patch (sometimes have to go all the way around the tube) and then let it dry for upwards to an hour (depending on what i'm doing) then patch, maybe a bit more of the glue around the edges just in case, then they sit overnight. Test them out the following day, Had only one fail, but that was because i failed at putting the patch on since I lost the puncture after I applied the glue.
