Review on Sawtooth Frame Hangers - 4lb Capacity, 🔨 Indoor Use, Set of 4, Decorate Without Damaging by Harry Tulsa

I don't know if they're fake but I've used two of them and neither worked. When I bought the originals from the store a pretty heavy picture fell off so I left the strip on all day before hanging the picture back on the wall and it worked (I honestly think maybe the instructions should say, that the wall will wait after wiping with alcohol to dry completely). When I did the same with these strips, both images still fell off. And one of them was very light, so the weight wasn't an issue. I think it's just quality.
