Our review of this DrinkWell360 Pet Fountain. We review its features, what we like and dislike and what the cats think. The cats enjoy using it and it holds 1 gallon of water. The adjustable flow is great and there isn’t any splashing when the water falls from the spout. We also like how quiet the unit is and it’s very study for our cats. There are no hard water stains or rust marks when using this product. We don’t like the fact that there is so much plastic making it harder to clean. The cost of replacement filters is also high but we have a solution for this. There is also a tendency for dirt to build up at the base of the bowl. Finally, we are going to create another video demonstrating the effort required to cleaning this fountain. All in all, it’s a good product but we are still on the lookout for something better.
