I had the opportunity to try a sample of the command outdoor light clips and I love these things.  my holiday light display consists of over 70,000 light so I am always on the look out for product to simplify decorating.  I used the light clips to hand light around my front windows and doors.  the old clips I had in place which required staples had dry rotted from exposure to the sun.  the 3Mclips appear to be much more sturdy and attach with out damaging the surface.  I already went shopping for more clips.
