Dont waist your time with the ones page manual. They fit my kid great! It works PERFECT! I love that it came with three different lengths. No back/shoulder pain felt when squatting! you need quite a few to hang pictures and when I was only used a few on all my bigger pictures (bigger than 8X10) The pictures would fall off the wall within a few weeks. Nothing hurts anywhere. For home recording I am very pleased. Bought as a gift for my mother. It is not sturdy in the least.
