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

I actually do recommend this, especially if you like sound machines that are strong and actually do their job. This one is definitely on the louder side, but in a good way. I already sleep with my sound machine turned up pretty high every night, and this still stood out to me in a noticeable way. I could hear it clearly from about 15 feet away, so it definitely fills the space instead of getting lost in the background. If you’re someone who needs consistent noise to sleep, block out other sounds, or just prefers something with a little more power, this would work really well. It’s not quiet or subtle, but that’s kind of the point if you’re trying to drown out other noise. Overall, it does what it’s supposed to do and does it well. WORTH THE MONEY and fairly easy to install. It does require those thick batteries so make sure you order that with this.

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
