This was great at first, but after a few months I had algae growth and you can not clean the inside. Plus, I keep it outside and the sun makes it brittle even through it was in the shade most of the day.

Pros: holds lots of water

Cons: can't clean the inside, algae growth, brittle outside

This is a great waterer to have outside in the summer. We keep it in the shade and the dogs have access to a lot of clean, fresh water in the back yard whenever they want. It remains mildew proof in the water container. A good time saver as you don't have to fill the bowl up constantly.

Pros: stays clean inside the water container

Cons: the big one is a little heavy to carry when full

I bought one of these and switched back to a bowl I change everyday. I still had to change the water everyday and even though I kept the water fresh, algea grew inside the container which was very hard to clean and I did not want my animals drinking from something with algea in it.

Pros: Holds large amount of water

Cons: Hard to clean

I love this product. It isn't big enough to last several days, so it makes me fill it up every day. This gives the animals fresh water every day. My puppy did get it apart though and chewed the bottom of the reservoir. It still works though. Very durable. Even puppy proof.

Pros: Not too big

Cons: Comes apart too easy

This is great for animals unless they have a bladder control problem, the pet never has to go thirsty. It is also transportable so it can go outside with your pet on a hot day.

Pros: Water is always available for the pet

Cons: chewable
