Best fountain yet...could be perfect with a few small tweaks
I have tried at least (counts on both hands) 9 different fountains for my two dogs and three cats. I’ve tried larger ones, hoping they wouldn’t need refilling as often (they are too awkward to carry to the sink to clean), smaller ones hoping they wouldn’t be as difficult to carry (they get slimy and need constant cleaning and refilling).

So far, this one is the best, although not perfect.

The size is very good. All five of my furfamily are well hydrated, so this gets a lot of use. With this size I add about 1/2-3/4 of a large pitcher of water a day. Because of the design of the top, you can add water directly to the top of the fountain, you don’t have to remove the top, like I did with other fountains. That makes it much more convenient.

I also very much appreciate the window that allows you to tell how much water is inside. There’s a small light on the pump that stays lit blue until it gets too low, then it turns red. Or I guess it does, I never let mine get that empty.

It is easy to take apart and clean, which I do about once a week. The filters are easy to change and they aren’t super expensive, which is good. Stainless steel is the only way to go for a fountain, in my opinion, as it’s easy to keep clean and more hygienic than plastic.

The fountain is extremely quiet. More than almost all the others I’ve tried. That is good, unless you enjoy the burbling of falling water, which drives me insane.

Addressing the lifespan of the pump, which I’ve seen mentioned in other reviews: this is a tiny little pump that’s also used in very small aquariums. It should never be run empty or with less than constant water flow. They are not particularly robust and will burn out very quickly without water. They aren’t expensive to replace and I always keep at least one extra around for that purpose. It’s just a fact of life. Should they last more than a few months? Yes, but sadly, sometimes they don’t. This type of pump is in virtually every fountain I’ve tried. Some are top discharge, some are side, but they are all basically small aquarium pumps. I doubt there even exists an industrial-grade pump of this size.

A few things that would make this much better:

When it arrives, the tube that leads from the pump to the lid is too long. You would have to bend the tube to get the lid on, which would a) make the blue light shine in the wrong direction and b) kink the hose, inhibiting the water output. Neither of those are ideal, so you’ll need to measure and cut the tube to the correct length.

Indents on each side of the water tub would make it much easier to carry the fountain. As it is, it is awkward to carry and if it’s full of water it’s easy to spill.

Please, for the love of all that’s holy, someone come up with refillable or at least reusable filter housings. Every time I change a filter I can’t help but think how much I’ve contributed to the trash problem on the planet. The fact that every water fountain uses a different style and shape of filter that all do the exact same thing is absolutely ridiculous. It couldn’t be that hard to make them reusable. While this one doesn’t use any hard plastic (which some do), the filters are still wasteful and won’t biodegrade.

Bottom line: This is the best I’ve had yet. I may get a second just so I can rotate them out or maybe so the furbs have more choice in where they get their water.
