Buying a £60 kit then standing there trying to figure out which set up is going to work is going to take a lot longer and be more obvious and it is less likely the criminal will have that equipment.
Obviously not having tried it myself but watching the video seems to suggest it would take ~10 seconds per attempt. There's only 5 variations less than a minute for almost silence seems ideal to me. Then again I'm not a burglar so what do I know
