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
Review: Great for telescope eyepieces - I use these on the lowest setting for keeping my 2" telescope eyepieces from dewing up and they work great. They seem to draw about 0.7A @12V or about 8W when cycled ON. But they are only drawing power occasionally.

### ⭐⭐⭐⭐⭐ Great for telescope eyepieces

### ⭐⭐⭐⭐⭐ Good Value!
*by B***M on January 5, 2024*

The heater works pretty well. I gave it 4 stars for temperature control because it doesn't vary the current, it just varies the time on and off. It always draws 7.7-7.9 watts when on, pretty low if using it on battery power. The difference between low and high is just the amount of time it spends on. I measured the following temps. Low 92-95F, Med 105-110F, High 115-120. It's also padded well so no chance of marring your equipment.
