we have 18 of these they work real well you don't have to go out and fill all the dogs water buckets everyday this helps out a lot. Every once in a wild a float sticks on a few of them but theyare easy to repair well recommanded

Pros: works well

Cons: float stick sometimes

Great for use in the yard, hooks right up to the hose for a constant supply of fresh water.

Pros: Connects to hose

Cons: None

This is great in the yard, no more carrying out water for the dogs only to have it dirty in a few minutes! Provides fresh clean water all the time!

Pros: provides clean fresh water outside

Cons: sometimes float sticks

We had a couple of these in the farm lot for the dogs. They worked great until the iron well water caused a lot of build up. The they had the be bleached out real well to be able to refill. We used them for one season. I would recommend if you do not have terrible well water, and have outside animals, it provides fresh cool water all the time.

Pros: durable, washable, constant fresh water, self filling

Cons: clogs with iron water
