After reading multiple reviews about this product, i bought 3 of the Large Command Hooks to hang my curtains. Followed the instructions accurately. The total weight of the curtains plus the rod was 3.5 lbs. Less than the 5 lbs advertised for this product. Waited for more than 6 hours before i hung my curtains. Less than 12 hours later my curtains came crashing down doing some damage to my floors. Needless to say, I will not use this product again. Now the wall has to be patched and painted. EXTREMELY DISAPPOINTED
