I purchased this filter summer of 2021 for three cats and they love it. The water flow is adjustable and there are different different discs for different flow options. I use the disc with four flows. I disassemble the fountain twice a week and clean it thoroughly, you can't expect the filters to do all the work. I change both filters monthly. You can't go wrong with this fountain.
Bought this less than 6 months ago for a 2 cat household. The pump has failed causing the water to trickle rather than flow, I change the filter monthly and the water still gets scummy. One of the three plastic holders that secures the cone to the base broke in the first month while cleaning. Extremely disappointed in this product, not worth the investment.
The plastic model is much better than the stainless steel model. The foam filter is insufficient. The third plastic grip is difficult to lock into place. It is difficult to center the pump
