The fountain is very pretty and could itself serve as home decoration. It works relatively quietly (at least in the 'slow' mode, the 'fast' mode is quite noisy, I could compare it to the sound that a refirgerator makes) and doesn't splash the water. The plastic pipe in the outlet was too long, but I cut it and now it's OK. My cat doesn't seem to drink more water from it than from a regular bowl, but she does use it, so it's not a problem with the fountain. When I asked the Seller how often I'd need to change the filters he told me once a month, but on the box it says once a week or so, which is not the nicest surprise. The parcel arrived extremely quickly and was well-packed. Generally I recommend this product, it's a good value for money for a ceramic fountain, just the information from the Seller could have been more accurate.
Not sure if its really needed if your water source is clean..
