I like having this because my girl drinks a lot of water and this way i can be sure she has some. I do beleve that the bowl should be cleaned often.

Pros: it is there for her all day

Cons: none

keeps the water bowel full and it is a releive that i dnot have to worry about my dogs running out of water. every other time i clean the bow and cotainner

Pros: keeps water bowel full

Cons: none

Made to last along time, and holds alot of water, the cats never have to run out of water and i do not have to fill it everyday!

Pros: made of heavy plastic, holds a lot

Cons: none

this way you know fresh water is availabel all the time

Pros: they have fresh water

Cons: none

this is a great thing if you have a few dogs, beats filling up the little water bowls 7 or 8 times a day!

Pros: works great

Cons: none
