Small and works as described
I use this for my uv wader repair. I don't tie many flies, but it's nice to use this on uv glue for waders and other random things I'm fixing. I used to just let things sit in the sun for a while, but this is way more convenient and I feel it's faster.
Overall I love the light; sleek, lightweight, lights up well. However, I could not get mine to initially work due to a small plastic cover between the battery and light, so the contact point was blocked. There was nothing on the package to indicate that this needed to be removed for the first use, so that was a bit frustrating trying to figure out for 10 minutes. So overall 4 stars for the quality of the light but the lack of detailed instructions.
The Nano light is nice because its compact and easy to carry anywhere my fly tying kit may go. Cure resin in no time. Push button would be nice over twist On/Off.
I bought the UV light to use in conjunction with Loon UV fly finish. Works great to cure the fly finish. Small enough to have on my tying desk to cure flies as I'm tying.
