The only time superglue is a problem that I have seen is when you haven't prepared the surfaces well. The thin likes to have perfect contact--no voids at all--and you have to watch for grease or oils. I have model airplanes held together with CA that have withstood 15 years of flying in all sorts of temperatures and humidity and G-forces. The only time it let go was after the full power on nose dive into the dirt---Well, it wasn't the glue that let go, but the wood in between, I guess.
I trust CA in the right applications more than about anything. For some stuff, though, it doesn't work at all.
