We've totally enjoyed this swing except for one minor design problem. The first one we ordered did not work so I ordered a replacement. When that one came it did not work either. So I troubleshot it with a voltage tester and found the the positive side of the middle 2 batteries (it uses 4) was not making any contact. I used a screwdriver to bend the contact pins out a little and it then worked fine. I'm certain this is what was wrong with the first one so if you have a problem getting it to work I would bend these 2 wires out a little and try it then.
