Yes, it works and it works very well. The water pump is virtually silent. I have noticed that my cat has been drinking more water since I installed the fountain.
It is also easy to clean.

Excellent water dispenser, the sensor is sensitive, my cats are delighted.

The cat water dispenser is very convenient and easy to assemble. It is made of stainless steel, and the power is connected via a USB cable to the mains using a 1 amp charger. There is also a wall-mounted indicator that shows when the cat approaches the dispenser, and water flows out, which is very convenient.

I love the fountain, my cats use it a lot and the water is always fresh; you can tell it's of good quality and I'm very satisfied with the purchase.

Perfect, this is the second one I've bought.
