I just received the Casfuy SY-WO8L smart water fountain. It is the second fountain I have had in a year. With that being said the first was a different brand . This time I considered the fountain more on how it worked and not on the way it looked. I really liked the way the battery worked on the Casfuy and the spout . My babies have always tried to drink from the faucet in my sink so I do believe they are going to absolutely love the Casfuy. So far everything has gone great today and in about 6mos. I plan to return and give another review. Thank You so much, Shontelle , Alex & the kitty’s

Seems to be well made and operates as advertised. One cat loves it, the other is working through her expected uncertainness about this new contraption but will be fine with it in a few days. It is silent and motion activated which will help battery last longer. It charged fully within about 1 hour after unpacking it. I'm sure that depends on the output of your charger (not included but plugs into any standard USB charger used for phones or laptops).

My cat is obsessed with fresh water so we looked at a LOT of fountains for her before we finally got this one. Setup was easy and the automatic mode is great. Once we got it set up, which was super easy, she was interested immediately and drank almost right away. I've never seen her drink for 6 minutes straight before. We've had it for a while now, works great and is easy to clean. Filters are easy to change too.

Our cat, who will be 21 in April, has some kidney issues, and we thought he would drink more water from a flowing fountain than from a static water dish, so we bought this fountain. It was easy to assemble, and it runs silently (except for the sound of the water). Over the course of a couple of days, our cat went from frightened to wary to curious to all in. We’re very pleased with the purchase.

Product came as advertised, and I love the motion detected water activation. The stainless steel design and look is nice and easy to clean. Only comes with one filter, so you need to buy more and they are a little pricey compared to other filters. But overall, it was a good purchase. My cats are still getting used to it because it is a new item to their eating and drinking area. They are proceeding with caution, I am sure in the next few weeks they will be just fine.

I love everything about this water fountain! It's so cool how it illuminates the blue indicator light whenever it is activated by me or my fur babies. They took to it right away. I think my cat loves it a little bit more than my dog. She seems fascinated by it turning on like it does (set on auto) and she will sit across the room and stalk it as if she's in awe. I'm hoping that this will help her get the adequate water she needs for a 16 year old cat with early kidney disease. Hopefully, this will encourage them both to drink what they need, and find joy in doing it with this neat gadget. Get your babies one. I'm sure they'll love it.

I love this water bowl. It helps Keep the water clean, especially because I have a Shih Tzu and her face gets dirty. When she drinks out of water. This always makes sure that the rest of the pets don’t have to drink her dirty water. I haven’t cleaned it yet but so far so good easy to put together. I don’t imagine it being difficult to up keep.

This water fountain is just what I was looking for ! I have a mama cat and her 4 kittens now using this fountain after they destroyed three other fountains. It works perfectly, stays in tact when the kittens try to remove the lid, and it is cordless ! The battery has lasted 4 weeks (and counting) without a recharge making it a convenient and functional option for my busy household. 5 Stars ! Wish I would have found sooner, but so happy to have made this purchase !

I've tried a few of the less expensive fountains that weren't stainless steel. They were also noisy, my cat was afraid of them since the water splashed out at her, and they weren't easy to keep clean. Then I tried a more expensive fountain that started out as great, only to have to replace the pump twice within a month after having it for about 5 months. Sure the pump was covered and sent to me at no charge, but my cat had to go without her fountain for a few weeks at a time. For that price, it just wasn't worth it. Enter Casfuy. I love it so far and my cat took to it immediately. So quiet, I keep checking to make sure it's on.

Go-To for Both My Cats

Excellent quality, easy to clean, works well, long charge (especially if you use its default mode to turn on via sensor). Both my cats drink from this fountain

Excellent quality, easy to clean, works well, long charge (especially if you use its default mode to turn on via sensor). Both my cats drink from this fountain now all the time! I completely sanitize it and put fresh ZeroWater filtered water in it weekly. It does come with a replaceable filter though (for any larger particles) which needs to be changed monthly thereabouts.
