These large capacity waterers are rust proof, dent proof, and easy to fill. The vacuum-sealed cap creates an automatic water flow. The rugged handle makes transport around the yard easy. Jar snaps compactly into base.
Pros - Easy to clean, has cap for spout so water doesn't slosh when being moved
Cons - none so far
I bought one for my meat birds and liked it, so I bought another for my hens. So far so good.
I think it's easy to take the base/tray off to clean; a bottle brush gets in all the little nooks and crannies. The hole in top is large enough to get inside to clean. I haven't had any trouble with the top being too tight/hard to remove (except the one time my husband screwed it on WAY too tight...) I like that the spout has a little cap so the water doesn't leak out when I carry it around. Yeah, it's a little heavy; but that's to be expected as it's 3 gallons. When we move the birds farther away for their ranging, I might have to put both waterers in the wheel barrow to move them when full. We haven't tried to hang them yet (and after reading some of the reviews, we might not). We just have them sitting on half-sized cinder blocks and that seems to work fine. The place where I got them from has replacement O-rings and caps , which is nice if I ever need them...
