Glues & Epoxy---What Do You Use?

[Super]

I know that the odds of the products we see on the "As Seen On TV" commercials are very slim to actually do what they profess but I am curious if anyone has used or heard if this product might works. 5 Second Fix sounds like a good idea as Dentists used ultraviolet light to cure their bonding agents however I am skeptical that if this is a good idea why has it not been mass produced and the idea used by other manufacturers. I like the idea of the adhesion not taking place until the light is shown on it and that it is flexible but I wonder if you would need three hands to use it or somehow affixing the light pen in a vice and holding the object with both hands over the light. Any ideas? Anyone try it?
