Review: Excellent dew-heater! - Works great at keeping the dew away! Lightweight and easy to pack; it lives in my astro kit year-round with a small battery. Troubleshooting: it's low draw means that SOME portable batteries will turn off because they don't think they're being used. If you think it's broken, try different batteries, or plug something else into the battery to increase the draw!
Review: Does what it says. - A simple item, keeps lens warm to avoid dew/condensation problems. Good Things: -Sort of elastic-y, seems to fit 50mm to bigger lens (see picture) -Will run all night on a large USB power brick, did not try with a small one -Has 3 power settings Where I live, cold is 35F, so I did not try it in the snow or where 'cold' is colder than that. Before using this I did have problems with lens condensation in situations where the camera/lens were outdoors overnight. This fixed that problem. Low worked for me (~40F) overnight. I did not try other settings. Did not use with 'star tracker'. Cannot speak to that, but I doubt that there would be problems. Bad Things: -None that I can think of

### ⭐⭐⭐⭐ Works good, but cheap quality
*by A***2 on November 7, 2025*

The product works good to keep my lens warm for long shoots outdoors in the cold and in the night. It does seem rather cheaply made, with some seams on it already ripped fresh out of the box.
