Although these magnets have a super adhesive force and can thus easily even attach photo boxes. However, the alloy bursts very quickly, even if you "staring them" the magnets only against the whiteboard or the refrigerator. This really arise nasty, extremely sharp cutting edges, where you also can easily get hurt, except that it looks ugly.
Have the magnets now no 4 weeks, and they've even used two or three times a bit to hang, but already has more than half a chipped alloy.
Conclusion: What good are the strongest magnets when they go the same broken even with careful handling? Waste of money ...
