I bought this to use primarily as a alternative to head cement for my fly tying. I think it's cool how the glue pen is at one end and the UV light is at the other. It's super easy to go from applying the glue to hardening it with the UV light. And it really only takes 5 seconds or so of the light to harden the resin. For fly tying, it makes a really nice neat looking head and it holds up great on the river. While I don't think this was Bondic's intended use, it works great and I am sure I will use it to fix other things around the house and such. I would definitely recommend this to anyone!
