I bought this fountain there are now more than 3 years.
At first I was changing filters, but now, for two reasons, the first is that I nétais not sure of the effectiveness and usefulness, and the second is that it was expensive.
I frequently wash my fountain and everything is going great for my 5 cats.
Please note that the fountain works properly long it takes approximately every 15 days, remove the small engine block (extremely simple), and of the descaling leaving him for a moment in white vinegar, this is indicated in the maintenance booklet.
Some cats drink in the tank, and others enjoy drink on arrival of the water, as they did before the tap (which was costing more in water consumption!)
If one day my fountain "makes the soul" I will renew my purchase.
