This fountain utilizes the twist-lock style of connection which creates a sure-grip environment that completely eliminates leaking. The Little Giant Plastic 3-Gallon Fountain is also equipped with a heavy-duty Metal handle allowing the user to safely carry the entire unit from it. Being comprised of plastic, this unit will not rust, rot or corrode. This unit is also very easy to clean and will not develop the strong smelly taste that transpires from metal galvanized models.
I would spend the extra money for a better waterer.
The water sometimes doesn't flow freely. You end up having to tip the waterer every couple days or so to refill the water basin at the bottom. If you don't tighten the water tray properly, you will end up with 3 gallons of water either in the coop or all over your feet.
Cons - the design is too heavy for very cheap hardware provided
Even without adding water to this, we could not use it because there were little fastner pieces missing. We used some things we had around garage. The water makes it very heavy and the metal rod broke right away. The water doesn't come out well, or we could have used it on the ground. But the reason we bought it was to prevent them from getting into the base.
Like being able to hang the waterer and it's helpful to be able to easily see the level of water in the tank. The problem we've had with this is that several times the bottom has fallen off right after filling, dumping water everywhere. Also, it's way too heavy (for me anyway) to put 3 gallons in it and then try to hang up again so we just put in about 1-1/2 gallons and then keep our fingers crossed that the bottom doesn't fall out while trying to re-hang it.
