SABRE Wedge Door Stop Security Alarm with 120 dB Siren - Great for Home, Travel, Apartment or Dorm

I purchased this doorstop alarm as I was a woman traveling alone on a month-long trip to Europe. I wanted to bring something to help increase my safety while at the hotels. I took the batteries out of this doorstop before packing it in my suitcase as I did not want the alarm to go off in the airport/airplane. After I arrived, I decided that the stop itself was handy enough without putting the batteries back in - so I ended up using it without the alarm feature. Though, the alarm is very loud and will definitely do the trick to alert you if you do put the batteries in. The doorstop is very lightweight, which is good for packing on a trip. The only issue I ran into is that some hotels in Europe have doors that don't have much of a gap at the bottom like doors in the U.S. have. Even so, I put the wedge up against the bottom as far as I could and it will still help. Also, there is a rubber bottom on it which helps grip the floor and prevent the stop from being moved if the door is pushed in. I'm glad I brought this doorstop with me for the extra peace of mind and the alarm feature is a great bonus.

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 alarm2) 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 inwardThe door is at a proper enough height to facilitate such an actionThe 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 floorsall 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.

Suena extremadamente fuerte. Detiene la puerta muy bien. Muy buen producto

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 !

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