I received the Fountain earlier than expected, much to my delight!  Assembling the fountain was extremely easy and was happy when the water started running into the buckets. etc.  BUT, I was very disappointed that even when it turned dark, the 3 led lights did not work.  I contacted Wayfair's customer service two days in a row to help me in resolving the "no lights" issue, with no resolution. They suggested I contact the manufacturer which I did, and they never returned my emails, etc. So I have a great fountain now without lights.
