Defeating dew is vital to most telescope users in Wales and my scope used to be festooned with cables, one of these boxes significantly reduced the spaghetti climbing all over my mount and OTA. Works well and not too expensive.

Kept the telescope dew-free all night in combination with the Astrozap Dew Heater Tapes 3" version

Great product ,well made and at a sensible price. Works really well and easy to use in the dark. Very pleased with this purchase.

great affordable little gadget ive seen these over £100 on most sites this is a well made piece of kit highly recommended

I've got this dew controller for a while and I'm happy with it, it works as described.
