Second year we set up our tree the bottom section went out! Replaced over 50 bulbs before they would come back on. Many were smoke colored. I does stay lit after bulbs go out but it has a limit. So tree was great again after 2 hours of pulling and changing bulbs! Decorated and enjoyed for 2 weeks! Top went out! This year was going to order bulbs. Site said contact customer service if ordering more then 3 packs. I did they sent me a case#00988551 They said someone would contact me. I received an email in troubleshooting! REALLY! I called customer service. After holding for 25 minutes I left a call back request. DO NOT BUY!
