Travel Door Alarm — 120dB Portable Wedge + Hang Security

Sleep securely in any hotel or rental with this dual-mode travel door alarm that triggers a piercing 120dB siren when an intruder attempts entry. The wedge mode slides under any inward-opening door to physically block and alarm simultaneously, while the hang mode hooks onto any door handle to detect vibration. Battery-powered and smaller than a deck of cards, it slips into any luggage without adding noticeable weight.
