Bests & Worsts Reviews from Amazon

I used these command clips to hang Christmas light (icicles) on the inside window sill and it is the best fit for the job. The clip is 1/2" W and 3/4" L, crystal clear, and able to hold two and maybe three 22 AWG cables (my icicles lights have 3 wire intertwined together). Before hanging the clips up, I followed the instruction of cleaning the area with isopropyl rubbing alcohol (not household cleaners), attaching the strips to the clips, applying 30 seconds of pressure to the clip against the wall, and waiting 1 hour before hanging the lights. So far, the lights are hanging up with no issues. Here are some warnings and notes on the back of package: 1) Do not use with wallpaper 2) May not adhere well to vinyl surfaces. Some window cases are made of vinyl. 3) Do not use for antiques, heirlooms, or other valuable or irreplaceable items 3) Do not hangs things over beds [There goes my idea of hanging a chandelier over the bed with these :) ] 4) Use only one hook per item hung 5) Apply to surfaces above 50F (10C) 6) Adhesive could lose adhesion above 105F (40C)
