I received this free product from 3M to try and then evaluate.  This is a great product.  I have a picture wall in my home and have used the traditional picture hanging products.  I thought a great way to try this picture hanging product from 3M was to replace some of the metal / nail hangers with the 3M product.  They were easy to apply and will not damage our walls.  I have never been disappointed with any 3M product and the 3M Command Picture Hanging Kit just reinforces my opinion of this company and their products.  I love this product, will recommend it as much as I can and will continue to purchase it.
