We test this product many times. The stickiness is strong to hold utensils. Below are some problems cause the item fall off.
1. The surface is wet when stick on it.
2. The surface is not a flat and smooth surface.
3. Paper wall, painted wall or dirty surface.
4. Hanging overweight items.
5. The first position is not correct, peel off and re-stick again.
(The adhesive back is not reusable, stickiness will decrease when sticking the second time!)
