They work and take up very little room in a seat bag.
Everyone here reviewing these patches love them, and so do I. These patches you either love them or hate them, the haters simply do not know how to use them. I've been using them for about 20 years and never once had one fail except on latex, they will not work on latex tubes. Like a reviewer said they work as a permanent patch, I've rolled on tubes with as many as 13 glueless patches, and some of those patches were 5 years old. I don't buy a new tube just because it has a patch, that's a waste of perfectly good tube, I just keep patching the tube until the tube is shot from either near decay, or the valve has some sort of issue, or I had to put a patch on top another due to a second strike in the same area which is rare.
The advantage to these patches is the ability to just buff the tube with the included buffer an area slightly larger then the patch will cover, then forget the step of gluing and waiting for it to set up which could take a couple of minutes, press the patch on hard for about 20 seconds and re-install the tube, and your good to go in less time then glue on patches.
These patches are also very thin and light, you won't feel the patch on the tube while riding.
This is probably the easiest patch kit to use. It works as it should on your average punctures, it's small so it'll fit anywhere, and it's cheap. What else is there? It's also a great way to make the $75 free shipping minimum!
These work surprisingly well, out of 3 uses (on 3 different bikes - 2 road, one mountain), all have been good repairs with no significant air loss afterwards. I figured they'd be good for a temporary repair and that I've have to replace the tube later, but I found that the repair was permanent and I'm still riding on the repaired tubes.
Small size leaves no excuse not to have it along. The patches work great for getting you home, when I always put in a new tube. I'm not sure how well they work long-term.
For years I rode my Gary Fisher Wahoo everywhere I went. I'm convinced there is no such thing as a convenient time to get a flat tire. With these patches in my pack, I am able to get back on the road, including pumping and everything, within literally 5 minutes of the tire going flat. For the price and convenience, it can't be beat. If applied correctly, it will last virtually forever as a permanent fix. I've only ever had one patch fail.
