Didnt get passed opening the box & seeing plugs on either end of the top  garland..checked the 2nd one too. When I called & ordered I made it clear I only wanted battery operated. As soon as I opened the box I call & explained & they were wonderful..agreeing with me that in the description it said "batteries". They were on the phone with me for a very long time looking for a similar battery operated set. I was told they would correct the description so this wouldnt happen to nobody else
