I've used Command Strips in the past and have been happy with the results, but these new clear strips are not as good as the old white ones. I use four of these on my kitchen back splash to hold utensils. The back splash is a plastic laminate. Out of four hooks, one has fell four times after a few hours and one fell after four days which is how long they have been up so I expect the other to fall soon. I weighed the utensils and the heaviest one is 3.8 ounces, less then half of the stated maximum weight. I have basically the same hook in white (The Command Small Wire Hooks) which has been supporting a 9 ounce clipboard for over 6 months with no problems. I also notice that the strips with those are thicker. I don't know if that is the difference between the two but the thicker ones works better, at least for me.
