A must have
This water fountain has made mornings easier by giving my Yorkie fresh water while I get coffee. The 3.5L capacity means I only refill it every couple of days even when she's extra thirsty. I like that it stays quiet and the cordless design looks clean on the floor. My pup seems more interested in drinking from it compared to her old bowl.

Quiet and sleek
I have used quite a few of these types of water fountains as my cats and dogs love them. This brand is very quality - they come with extra filters and look nice as well. This particular one is also silent, which is nice since it is now in my living room.
Verified Purchase
It took a while for the kitties to get used to the oneisall water fountain. I love the motion detector feature. The filters are expensive. However, I was supposed to get three filters with the product but it had only two. Good product. I recommend it.
