Review: Well worth the money - Excellent magnets, they are about the size of the batteries you put in various car alarm remote controllers, and are quite strong. I used one to hold a security camera to the ceiling and it does the job very well. I don’t think one could hold 8 KGs, but two together may be able to.
Review: Strong magnets - Excellent, required to attach a flower to a handbag for a wedding. Worked perfectly, magnets really strong. Delighted with purchase
