They work perfectly fine (the park GP-2's that is). I've been riding on a patched tube with one of these for the last thousand km's and it's as solid as a "real" patch. These are 23c tires inflated to 110-130psi.
Agreed. Some people apparently have the "magic touch" to make stick-on patches work, but I sure as heck don't.
You really should try them again (park GP-2 once again), on a busted tube. The key to those instant patches it hat the tube MUST be inflated a small amount and like "real" patches the surface needs to be clean.
The advantages of these patches are awesome once you can use them effectively. You don't have to wait for glue to dry and you don't have to mess with anything and it's fast.
