I purchased that waterer last fall & used it all last winter. I really like it, and am going to be getting another one this year. It's easy to use, the plug is extremely safe (sort of embeded into the base). I was using a heated dog dish before that, but birds with long wattles dip them into the dog dish and they can then freeze. THIS waterer has a narrow drinking lip, so wattles can't dip into the water & get wet. I put mine up on a cinder block in the coop, and it stayed very clean all winter long.
