Cons: leaks, unsteady, easily soiled
I purchased four of these for brooder boxes and from day one have hated them. Unless they are perfectly level (which is impossible on top of pine shavings) the water runs out and soaks the bedding. It hardly weighs anything, so bigger (3 week +) birds knock it over easily. There is ALWAYS droppings and shaving in the water. When the birds are small, they step in it and poop, and when they are larger they perch on the top and do the same thing. Even the small chicks fill it with shavings within minutes of being in the box, forget the older birds. The water will NEVER be clean, it takes them about two seconds to dirty it up after you clean it out. I wouldn't leave the house for more than a few short hours because I knew when I got back none of my chicks would have water. Even over night I would get up and clean them out at LEAST once, usually more.
SPEND A LITTLE MORE AND GET A WATERER THAT WORKS!!!! IT'S NOT THIS ONE!
