Lens Dew Heater Fog Remover Strip with Temperature Regulator 5V USB Warmer for Universal Camera Lens Telescopes Eyepieces Heating

Works very well no dew formed on the lens by the end of the night.

Works great and fits camera and telescope as it has Velcro strap. Great build quality great price too

Easy to fit & adjust heat levels . But bear in mind you need to provide a power source so an extra expense if you don’t already have a suitable power brick.

Works perfect on my Telescope (Mac Cass) even on the lowest setting. Would suggest buying a good powerbank (YOBON 30000 mAh).

Excellent

Brilliant product.Works perfectly.I would recommend getting a decent power supply as it uses a lot of power which is expected. All in all, great product

Great product at a good price. Very well made

Works well in my limited experience. Have been out on December evenings a few times to get star trails. Frost settled on me but the camera lens stayed clear so happy with it.
