Staying in hotels can be dangerous with various people entering your room at all hours of the day to clean it, fluff your pillows and do weird things to your toothbrush. If you’re worried about intruders when you’re not there (or while you’re asleep), check out the Travel Door Alarm from Belle Hop.
Armed with a 91dB alarm, the Travel Door Alarm hangs around your room’s door handle and has a little sliver that slides between the door and the frame. When someone opens the door and breaks the connection, the alarm goes off, scaring the intruder away and alerting anyone nearby.
Plus, there’s a sweet flashlight built-in! $12 is a paltry sum to pay for peace of mind while traveling.
