Setting this up took about 10 minutes at maximum. It's because of me I had to read throughly. It took time for my cats to come around to drinking out of it,only because they're not used to water fountains. The product itself is amazing and runs very well. But one day I saw one if my cats finally come around to it and drink out of it. I like that you can change the setting of how much it dispenses water. I have it on the lowest setting for my cats because it's best for them. I love it for my cats and it's worth it.
