Regular crazy glue won't hold it very long. Get the stuff specifically for mirrors. It's probably a cyanoacrylate (like crazy glue) but it's thicker.
anything but the real stuff made for the job will fail quickly. it's not a hard job and the "glue" is very cheap. i can usually find it at a local walmart or drug store (living in south florida, the heat eventually gets to them all, so it is easy to find the adhesive pretty much everywhere, lol)
