I've had them since the spring and have been itching to put them up all this time! I have another set which was made up from "bitsa" and has ended up with 14 rather than 12 lamps and is on permanent display (but not switched on all the time of course!) in my workshop on the edge of the uppermost shelf.
I did try to put the 12 lamp set on a very small tree but the tree was just too small
