The tree arrived very quickly and all seemed in order until I plugged it in.  I noticed that the tree, which has a nice shape and ornamentation, only appeared to light up in a solitary "white light".  My first thoughts were that I must have inadvertently ordered the wrong tree, for I expected it to constantly give an ever changing color array.  That's when exploring further, I realized that the "innards" of light and wheel pedestal were rolling around inside .......color wheel, nuts, bolts, washers.  After taking it apart, though I found it near impossible to screw the wheel in place (tiny, tiny screws upside down, ugh), I was finally successful and have greatly enjoyed the tree.  Just the right size and very colorful indeed.  So, all's well that ends well - it's perfect.
