Strong magnets, one is enough for a 2.20 m high cupboard door to hold and worn. If the magnets are mounted horizontally, the magnetic force is stronger al vertically. (Perpendicular I had a single door, where I also had a partition inside) Did the magnetic snapper then mounted horizontally above and it worked great. Screws are not always complete and sometimes rusted. The processing of the internal magnetic disk was not always optimal (times too small = falls out sometimes, if not already mounted and times too big = no free movement of the magnets. The case looks very valuable.
