All good - works well. Cat played in it originally and then figured out it was for drinking. Now uses it regularly for drinking, only playing in it occasionally. I have not tested the low water alert or filter replacement yet. So far so good though. I did have some initial trouble installing the small plastic filter but seller helped out promptly and all sorted.
Awesome dog fountain, totally quiet! Water level is sufficient for the dog to drink without problem. Happy, thank you!
