It is easy to use and thus far I have used it for pictures, photos, speakers, and even entire paintings. Just follow the directions and you will be set!
We had never attempted to use this product. We are 'old school' and always used hammer/nails to hang things on the wall...until we moved into our new home. I didn't want holes in the walls. A friend suggested the Command Strip products. I had no idea of the scope/variety of availability !!!
So far, we have used the picture hanging strips to hang 8 canvas of different sizes. They're all still exactly where we placed them :-)
Since then, we've used other Command products in the closet, kitchen and office.
My laundry area is in my unfinished basement. I love the strips because I can hang things on the concrete walls that help me keep the area organized. I highly recommend the strips.
