I have tried 3 times and the product has failed 3 times to hold a hair dryer that weighs 1 lb. I am using medium hooks. the first 2 fails were with strips I purchased years ago, so I assumed the failure was due to old product. However, I purchased new medium strips with new wire hooks (17068) and they failed as well. they just fall off of the wall after 6 or so hours holding the dryer. Perhaps it is because the wall was painted within the last 6 months, but that is not noted as a problem on the packaging. I am an engineer by degree and am able to read and follow directions, which I have done. the project has simply failed in my application.
