Product review (5 stars): We really love them--bought two more sets this year for more house coverage.
Very nice.  Even if you hang some of the icicles so that the LEDs face toward the wall instead of outward, the play of light against the wall is stunning--gives an "Aurora Borealis" kind of effect.

Some people speak of winds knocking these down, but it really just depends on how you hang them.  I don't use the plastic clips; I hook them to tiny nails by the wires, and if necessary twist a couple of "twist-ties" (like a bread wrapper uses) on some of the nails. I can hang the quickly even with the need to do it on a 20-foot ladder. Today we had 40mph winds (actually I think my house saw only about 30mph gusts) and the icicles are still in place....

Anyway they look fantastic.  Also, in the daytime they look great too because (unlike many such products) they actually look like icicles.
