I received this product for free from 3M to evaluate.
While it was more expensive than a traditional nail-in hook, it was very useful to temporarily hang up a heavy coat and/or towel.
When I wanted to remove it from the spot, it came off the wall somewhat easily, without leaving a mark.
When you consider the time that you would need to spackle, sand and re-paint an area if you used a traditional molly bolt or shield, the extra cost upfront was well worth it. [This review was collected as part of a promotion.]
