W&W Astro dew heater, 30 cm, for 3" telescopes

Fantastic product, I've used it and it does the job perfectly, it was a pleasure dealing with this company also, they went above and beyond to ensure I was a satisfied customer, the item arrived quicker than I expected and was well packaged for a great price, if you're interested in their products and are shopping around, look no further, you won't get better anywhere else

Great item. Cheaper and looks better quality than the well known brands

Very good

All good.

Wrapped it around my Canon 24 - 105 L lens for a night timelapse and it keeps the dew at bay. Excellent : )

Excellent heater. Use it on my nikon camera lens when shooting nighy photography. Power it from a battery and it gets plenty of heat from it.

I have used it a few times and certainly iit gets warm and no condensation on the optics. Great

Works as it should and cheaper than the bigger names.
