I just got it but do love that it plugs in! Think this will be much better than the battery operated one, then they had discontinued the filters. I had it less than a year, with my previous cat she had one like this and never needed to get another one! I like the look and that it’s stainless steel!

Great water bowl

Quiet. Keeps water moving. Cats adore it. Better than other fountains we’ve had. And the price is good. Including new filters
