SABRE 120 dB Wedge Door Stop Security Alarm, Extremely Loud Wireless Alarm Siren Audible Up To 1,500 Ft., Non-Skid Pad, Compact Alarm Great for Home, Travel, Apartment or Dorm

Very Loud when you use the siren. Also effective without. Of 5 different safety systems for hotel or guest room stays. This is my favorite.

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.

This gave us a lot of peace as we were traveling as a family in different hotels on our recent roadtrip. Safety is always worth it! Buy this! Works just as described and is relatively small to pack.

Well, this definitely works, it might work a little too well. It’s very sensitive. I had to take my dog out in the middle of the night at the hotel I was staying at. When I came back, I went to reset this and put it into place and it ended up going off and causing quite a panic at the hotel. It’s extremely loud, which you would obviously want if there was an emergency.

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.

Make sure your door is low enough so that it presses against the lower front tip portion of the silver aluminum trigger of the alarm. If your door sits on an entryway lip, so it's elevated in relation to the inside ground level, and hence will only touch the higher back end of the silver trigger when opened, then the alarm will not sound off. In other words, you would think that having any part of the silver aluminum trigger being touched by the door would set off the alarm, but that's not true. Only the front lower tip area activates the alarm, and not the back part that's higher up and closer to the alarm speaker. Otherwise it seems built well enough for the price. The alarm sound is very loud, no way you won't be woken up to it.

I recently purchased an alarm doorstop, and I couldn't be happier with my choice! It was incredibly easy to put together and came with a convenient QR code that provided access to all the information I needed. The doorstop requires a 9V battery, which was simple to install, and I was able to start using it right away. The functionality is impressive; it provides a robust alarm that enhances security without being overly complicated. What I love most about this alarm doorstop is its durability and portability. It's lightweight and easy to travel with, making it perfect for hotel stays or visits to friends and family. Plus, considering the great price, it offers fantastic value for the security it provides. I highly recommend this product to anyone looking for a reliable and effective way to enhance their home security while on the go!

It works really well. Just make sure that you don't turn the switch on before you put it under the door. You will have comments from the other rooms in your hotel lol. It's 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 !

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!!!!

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

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

I like this. Not just a regular door stopper, it also has an alarm function, which makes it much more useful for home travel or even apartment use. Once pressure is applied, it gives off a very sharp and loud alarm sound, which is exactly what I wanted from that kind of product. It's simple, easy to use, and gives a little extra peace of mind.
