SwitchBot セーフティアラーム

The strobe light is what sold me—it keeps flashing for over an hour, which is reassuring if you need to leave it running while you call for help. The alarm itself is loud enough to wake the whole house, so I feel a bit safer knowing it's by the door.

The strobe light flashing for over an hour is a huge plus, and that 130dB alarm genuinely makes me jump every time I test it. It's a bit larger than I pictured for carrying in a pocket, but it sits fine in my bag.
