It really works
Took this on touring holiday of Vietnam and Cambodia and as two women travelling we definitely felt safer in our rooms, would use when staying anywhere UK included, set it off by accident a couple of times when forgot it was under the door and it is really loud!!!!

Objet qu'il faut posséder absolument ! J'étais septique, mais plus maintenant ! Vous entendez l'alarme à plus de 100 mètre ! Très forte résonance tout le quartiers entends ! En plus de bloqué la porte ! N'hésitez pas ! PS : Prévoir une pile de 9V ! Dommages qu'elle ne soit pas fournie ! Mais vu la qualité de l'appareil, aucun soucis !

These are great and loud! Perfect for serving its purpose! Con: when you turn it on, I wish the little light stayed on, so I would know that the battery was still working and that the wedge was in the on position when I’m in the dark.

VERY Loud door alarm. However it somehow ran out of battery after one use as it was travelling in my backpack

Purchased these for traveling, as I assume most do. We've used them for close to a year now in hotels both in Canada and the US, and Air BnB's. They work in two ways: 1) The metal plate completes a circut which trips a loud alarm 2) The wedge shape allows for blocking of doors that open inward by jamming the door "up" and binding up the hinges, barring physical entry. This is dependent on a few factors: The door opens inward The door is at a proper enough height to facilitate such an action The floor surface is grippy enough to not allow the device to slide. They work absolutely well, with a few caveats, but first the positives. Pros: The are loud (almost debilitating in small rooms) , don't take up a lot of room and are pretty simple to use. Cons: They won't fit under all doors due to the height of them. Some doors are too low, others too high. On some surfaces they will slide, because you can't get a good wedge because pushing it too far under the door will trip the sensor. By attaching two together with an elastic band, I have managed to make them go off, but not block the door to an effectiveness level that I felt comfortable with. They would work well for waking occupants, provided those occupants are prepared to do something about those person or persons are gaining entry. As a simple stand-alone deterrent, I'd rate them on a 3/10. They won't stop someone determined to gain entry, but they will keep the honest crooks or mistaken housekeeping away with no issues. For improvements on these I would like to see a method of attaching a tripwire/string to them that can allow the same action of a door opening and depressing the metal trigger to trip the alarm. This is useful for times where they won't fit under doors, doors that open outwards (but you'd still like to know when they are opened). Upgraded and expanded grippy material on the bottom to facilitate better sticky action on floors all in all, if you're someone who wants extra piece of mind, one or two of these in your bag is never a bad idea.
