NPET Cat Dog Water Fountain PIR Motion Sensor Switch for Pet Fountain

I got the first one, with my first WF020 fountain, 16 month ago, in March 2022. I already had a fountain but I wanted a second water supply for my two cats and my big dog.
It's just a must have accessory. With this, the fountain only works very few hours a day, only when needed instead of 24h/24. So I'm saving water (less evaporation), saving electricity and saving pump lifetime.
I'm so happy with it that I bought a second fountain with that motion sensor in November 2022 to replace my still working old fountain.

I found that if you have a fountain with a USB end connection, this product will work with it well. Nice products!

I cannot evaluate the item purchased because my order has never been delivered. However, I can say that the service offered by the shop is very bad: untraceable shipping and delivery not made. I now have to understand how to recover the amount already paid.

Crap

Motion sensor worked fine for a couple of days then stopped working. Contact the company but received no response.
