My cats like to use this product. I think it works well. Must keep pump fur-free to ensure a good flow, but the submersible pump is powerful enough. Filters are easy and inexpensive to replace. I use bottled water for this product. It holds about 1 gallon of water in total (reservior and bowl together). Great product. Silent pump unless very low on water. Should keep water reservior full to avoid burning out pump. Highly recommended.

Pros: Keeps water fresh and clean. Has in-line power switch. filters are inexpensive and last for a few months. Comes apart easily for cleaning.

Cons: must clean fur from pump and periodicly change filter

This works well for most of my cats, I do have one that likes to play in it though. Keeps water clean and fresh, a bit of an energy waster though. I guess the justification is their water is much cleaner, less bacteria in it and they drink plenty of it which can be a really good thing healthwise.

need to update, the ratings not working well these days, I rate this thing at a 5, not a 1 sorry

Pros: Clean water all the time

Cons: some play in it, need to replace filters

this is great just like the other fresh flow but this one is very ideal for alot of animals and large dogs who drink alotand once again is even more expensive than the other one is.

Pros: everrything is great

Cons: price

I think this is good for just cats...but cats AND dogs...it's not very durable. Maybe that is saying something for my zoo. After about a month or so it started to fall apart and leak. We kept up with keeping it clean but it just couldn't keep up with it's durability

Pros: Keeps water Fresh

Cons: Not very durable

Convenient for owners and for pets as well! Works well for the finicky drinkers! My cat loves to drink out of the faucets in my house, so this water bowl is a natural fit for her. I change the water twice a week and change out the filter every month. Easy to use!

Pros: Convenient, filtered water for finicky drinkers

Cons: N/A
