I really appreciate a lot of the features of the Premier Pet 60 oz. Pet Fountain. I have tried another pet fountain that leaked and got filled with dog hair and other yuckies. So I love that this product addresses a lot of the issues I've seen with other pet fountains. Not only does it have a carbon filter so that your pet's water is clean and tasty, but it also has a foam filter to remove the inevitable dirt and hair that your pet gets in its water bowl! The flow control knob allows you to adjust the speed of the fountain, and also helps to prevent bacterial growth. It was pretty easy to set up and the nice soft sound encourages my pets to drink!
