The concept is pretty awesome. The mechanism attaches to the inside of the door with screws or adhesive (I recommend screws, my stickers were finally pulled out by force children to shoot the doors), and will block the gate unless the user places a button containing a magnet facing the mechanism, outside of the door. Result: nothing to attach to the outside of the doors of the kitchen leaving intact the look, possibility of leaving the magnet in place and therefore have doors that open tt time when cooking ... and finally, a small button can permanently disable the system. Not even need to disassemble qd children are grown. A weak point? The assembly is complicated. We must take time to get everything in the right place and therefore effective.
