I purchase this product along with the Large (5)lb about 6 months ago. We had just finished remodeling my son's room with new paint and sheetrock. After letting the room go bear for several weeks we were confident that 3M Command strips were the way to go, since they claim "damage free", however I find this claim is untrue. The day before yesterday, my son brought me his medium size plastic wall clock and with his command strip plastic in hand he say, "MOM!", with a look of disbelief in his eyes. His command strip had broken, peeling his new paint off the wall. It just fell. Then today the large one that was holding a medium size wooden picture frame did the exact same thing. I am very frustrated that now I will have to repaint the room and possibly have to do some plaster work. I love the idea of no damage walls, but if you cant stand by your product and make it right then, you are not worthy of me spending my money on your product. Thank you for my rant, but one upset momma tonight.
