Title: Doesn't work well on plaster
Review: You need to have a very smooth surface to use this. I wanted to give this a try based on the recommendations. Unfortunatley with the plaster walls I have, the performance was not even there. The texture of the plaster wall will make the magnetic stand up in the middle where there is absolutely no nails or studs for that matter. I will try it in the future on modern walls to see if it works as advertised. If you are working on plaster, use a real stud finder.
