Bests & Worsts Reviews from Amazon

I don't know where all these wonderful reviews are coming from or what I did wrong(I followed the direction to the t) but I so regret buying this product. I used the largest hook to hang my brand new 30lb clock. Everything looked fine and sturdy when I was done. I was pleased with the outcome. I went to do a quick grocery shopping and when I came back, my clock was lying on the floor, broken! I am really angry at myself for buying this instead of using nails like I did with all my frames and canvas. This hooks are useless! Don't buy it!
