The tree was a real disappointment. It didn’t look anything like the picture in the advertisement. To begin with, it wasn’t full at all as pictured. Instead it was so skimpy and the branches were spaced so far apart until the skinny trunk could easily be seen. Then, the assembly instructions could have been written in more simple, direct language. I still don’t know how long the bulbs will last, or if the replacement bulbs can go on any section of the tree, since the extra ones were attached to different sections.
