I have their Heat Lamp, Premier 1, I had to use over 3 days during our -30 to -40F temps last winter. Glad I bought it. I was not concerned at all using it to keep my girls comfortable during our Polar Vortex. Look it up, very safe if you need to heat in SUB-ZERO temperatures.
I like their heat lamp too, much safer than the old metal type. And I'd love the electrified poultry netting, if it fit at my coop!
I order many of their fencing supplies and have been very happy with them.
