I have ordered other fountains from Wayfair and they arrived with all of their parts, worked when plugged in, and the stream and sound of water were great.
This fountain arrived without an electrical plug.  I called Wayfair and was told they would send a plug.  Instead, I received another fountain.  My second fountain was clearly a return item (the hard foam was in pieces and the box was re-taped many times).  After I cleared small pieces of styrofoam from the fountain, I filled it with water, plugged it in and got less than a trickle of water flow.  Not want I was hoping for.  I then tried the plug with the original fountain, and that fountain didn't have any water flow.  I am disappointed with this product. I will re-pack the two fountains and return them to Wayfair.
