I have four and love them. No freezing water in the winter and no fear of shocks. No algae and gunk in the summer, no standing water for bugs to breed in, and no troughs for horses to try to climb in and flip!
They are fabulous, one of the best things I've done as far as helping myself out on the farm.
Please don't try to be a voice of reason. It's way more fun to spin things out of control. #BecauseCOTH - showhorsegallery
I love mine. We have two different types, the Bar Bar A and the watering post. They both have pros and cons. IF I did it over again I would only have one or the other.
the Bar Bar A works well, and the horses find it easy to use. It does have a filter that needs to be cleaned every so often, but it is a very quick job and takes 15 minutes a year. They can freeze up, I check mine everyday year round, but sometimes in the winter they will get some ice build up in them. I just take out hot water in a milk jug and pour it in to thaw. It is caused by snow build up and very cold temps. IT is soooo much better than the alternatives. I had a friend put hers in a huge run in area and they never have that issue. The neatest thing is, the horses love them. They love the fresh water that is cool in the summer and ground temp in the winter. They prefer it over buckets in the stalls. Good Luck if you get one, I love mine
The watering Posts are very good also. They are higher and do not have any filters to clean. They ice up too, but usually they all do at the same time. I have some horses that find them harder to use as its a smaller bowl and the paddle is harder to push down. They look very clean in the field though. A very small pony would not be able to use it because it sits up higher than the B B As. On the other hand I had a large pony here that would stick his foot in the Bar Bar A. He clogged it up with gunk from his feet and that is why we then went to the posts. He is turned out in the field with the posts and the Bar Bar A has a blue plastic barrel around it to keep feet and hooves out!
FWIW,when I was looking into getting auto waterers, the Bar A rep told me that you need more than a few horses drinking from them for the waterers to function well. If you only have it for one or two horses, it might be worth double checking with the company.
