To be fair, I keep my magnet on my fridge and just take it off and open the cupboard. Takes me 2 seconds and isn’t really a faff for me. But then I’d rather a bit off faff than my child being able to rip open the other locks we used and getting into my cleaning products, plates ect though. I watched her video though and she does make it look really awkward to use.
I’d say the only faff of it is if you put the magnet down and it attaches to something and you lose it. We lost ours one day and found it a week later attached to the hand blender
Thankfully we have a spare magnet.
