Just set up the fountain…exactly what we needed! The cats loved it immediately. We bought this to help with constipation (which happens in middle aged male cats). It is much quieter than I thought it would be. My background is in Electrical Engineering, so I appreciate the effort put in to develop such a simple design using high quality components. We did have a fountain previously, but it was hard to clean and very loud. After researching your product, it definitely meets and exceeded my expectations. Well done!
