Pros: Easy to fill, never froze, no leaks/spilling
Cons: Can't see water level
This has been a lifesaver, living in the midwest. Last year we used the heated plastic waterer and it was a source of constant frustration. I dreaded changing it out every time. It seemed that more times than not, the base would come loose and water would spill all over the coop, requiring removal of bedding and fresh shavings to be put down.
This year, we bought this with the heated base-what a difference! It is easy to carry to the pump, fill and set back up-with OUT ever having water spill everywhere in the coop!
Temps reached -20 and never had issues with it freezing either.
