Very expensive bowl of water. Can’t even use asa basic bird bath, because when the pump stops working all the water drains into the bottom bowl.  Pump does not work as demonstrated on Wayfair site.   Also Filter unit clogs with a little debris, like some pollen—every day.  We had to modify with netting, but pump still barely moves the water. This site won’t allow me to download my video. UPDATE I chatted with customer service and a replacement pump is on its way!  No matter what, Wayfair Customer Service is the best!
