When I plugged this into my power board, it messed everything up that was plugged into it. Anything metal on my telescope rig would electrocute me. If you are going to buy this make sure you have a completely different extension cord to use it.

Used for due prevention on the lenses of telescopes and cameras. Its soft and wraps around the lens easily, also the cable is fabric which makes it very flexible and easy to manage. It has three heat settings and an on off switch. It runs on any USB supply of 5V and 2.5 amps or more.

I ordered the 400mm long heater for a 127 Mak but on unboxing the strip realised it was too short, the OTA is 140mm diameter.
I did not return the item because I can use it on my 90mm refractor or extend the velco wrap.
The item appears well made but I haven't had the need to use it yet, its summer here and most viewing evenings are still above 20degC.
