| Comment | Well, whoever is saying it is [full of shite](https://www.screwfix.com/p/briton-9551-single-magnetic-door-lock-unmonitored-door-status-12-24v-dc/2581t).
Nobody is stealing these to sell on. They are cheap, worthless second hand and are no use when not connected to a power supply.
You can pick up a proper magnet for trawling in rivers for £5-£50. |
