SABRE120 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

Loud and long lasting. We bought this a second time. The previous one still works even after five years. The device is long and tapers to a very slim end so that it can easily fit under doors even if the gap is small. Slight negative: although the device is heavy, it is still necessary to brace something heavy against the alarm so that an intruder cannot open the door slowly and quietly the device slides away with no alarm sound if the floor is wood or ceramic.

The battery has to line up and its opposite attract situation. Simple once you get your battery in.

Oh my GOD! This this is stupid loud and stops the door from opening any further! I doubt very much that anyone who tries to enter will leave soon after!

I didn't need to use this alarm doorstopper although it traveled well. I would suggest people tape the button where the ON and OFF button so the alarm doesn't get turned On accidentally due to jostling around in the suitcase. It works well with carpets or wood floors.

LOUD! These are certainly going to wake you up if the door opens. I can't seem to use them in my house, but they would be great for a hotel room.

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!

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.

The media could not be loaded. Excelente tiene una alarma ensordecedora a pesar de ser pequeño estoy segura que asustará a cualquier intruso.
