“I recently purchased this heater for keeping minnows from freezing in a cooler in my garage.. it works perfect until the temp gets below 32 deg. Then everything goes south from there.its only about a month old and quit working.”
“This was such a great idea and has made my life so much easier that I bought one a few years back and then bought this one as my old one had run its course. I can't imagine, in this cold cold weather, not having one! And it goes so well in the waterer bucket I got from here too! Love Love Love it!”
“Got this for my girls. Living in central New York, we often have cold weather. This keeps water warm when it needs it. Does not seem to be in when not cold. Also helps with moisture if not heating all the time. We do use watering cups attached to five gallon bucket. When real cold the cups still freeze though. But this I expected.”
