When you're in a new place, an added measure of protection can give you peace of mind to sleep better at night, even if you've locked the door. This reliable and powerful alarm will give you that peace on mind whether you’re traveling or staying at home. With a motion sensor that triggers the alarm when someone has opened the door, it can be used in college dorm rooms, at hotels and hostels, or even at home. With two lithium button cell batteries included, it comes fully operational and ready to use. The sound intensity level of 91dB is loud enough to hear throughout the room and will startle the intruder. No one will be able to get in or out without you knowing. It’s easy to set up: while holding the thin blades together, simply slide them into the crack between the door and doorframe, then loop the cord around the door handle and adjust the toggle to keep it in place. Lastly, set the alarm. This same technique can be applied to sliding doors or to windows as well. No matter the situation, it will alert you to a possible intrusion. Additionally, the built-in bright LED flashlight allows you to see your way around in the dark without having to turn on lights. As a compact, lightweight option, it will also take up very little room in your suitcase or handbag. If you have loved ones that travel, you travel yourself, or you’d like an added sense of security at home, this travel door alarm will alert you if anyone tries to get into your room without your knowing, and can be a lifesaver in unfamiliar situations.
