I am selling this item because I no longer need it due to a move. I purchased it from the SwitchBot official website in July 2025 and used it for about 3 months, as I moved in October 2025. Since it has been used once, the adhesive on the magnet is quite weak. I think it would be better to replace it with an alternative. It's a better deal than buying it at the regular price! Would anyone who doesn't mind this be interested?
