I could not be happier with the Drinking Post waterer. After having several issues with a competitor’s automatic waterer, I can say with enthusiasm, this waterer is worry free. There’s no need to mess with broken sensors or running electricity to the unit like other waterers require. Plus it’s been no problem for all my horses to learn how to use, from small ponies to new born foals. Also, the Drinking Post has a knowledgeable and helpful staff to walk you through the install (which was simple) or to troubleshoot. Thanks for a great waterer. I highly recommend the Drinking Post!
