Hi, I bought two before winter, I love mine. We have a heated water base for our girls, but I needed a thermocube for our roos, which are housed seperate. My DH made a couple of tin water heaters and we have them pluged into the cube. Our cube turns on at 35F and off at 45F. We have had some really freezing temps here and the cube does a great job of keeping their waterers from freezing.
Each one has two recepticals and I ordered them on Jefferslivestock.com for 10.95, when I was ordering other pet supplies.
