Sanjie Door Window Alarm Sensors, 5 Pack, 125dB, Volume Control

It works as intended, however I have to warn people not to install this around kids/babies/toddlers/pets and if you can wear ear plugs because it’s been four hours and my ear won’t stop ringing since i briefly heard the alarm. It’s very frustrating and is showing no signs of stopping. There is no doubt I can hear it from my window well in my basement to my third story even with a fan. It sounds very legit and if I didn’t know better I would assume it was hooked up to a professional security system. I believe my neighbors would hear it in their own house, it’s that loud. This would be great for people with curious toddlers or kids who you fear might sneak out the door. You can set it high and they can’t reach it, the sticky tape is very impressive and strong. It works, gives me peace of mind.

Perfect for your peace of mind! I cannot get over how incredibly loud they are. Easy to install, we 100% recommend these alarms.

HAVE THEM ON ALL MY WINDOWS AND DOORS VERY GOOD PRODUCT AND DOES EXACTLY WHAT IT SAYS THEY ARE THE ONLY KIND I USE.

These door and window alarm sensors are good and do the job. They are easy to install and use, and the alarm is loud. I also like that you can adjust the volume. The 5-pack is useful for putting sensors on different doors and windows. Overall, they work as expected and are a simple way to add some extra security to your home.

Super easy to install, my son is autistic and he wandered out of the house and Mom panicked. I bought these and now we feel a lot safer. And they are super effective

Really easy to use and install, I really works and instantly, the adhesive is great, I comes with two different volume tones and doesn’t look bad wherever you put them

Couldn’t put zero for a rating unfortunately! Not one of the Door Window alarms were viable. Wouldn’t turn on at all. I think ALL the batteries were dead as a door nail. Really very disappointed, so sick and tired of China garbage..

Simple alarm that will alert me if I have an intruder or my grand kids try to escape.

Used on my doors and windows after an attempted break in. Super loud, there is no volume control so you can turn it down and I swear it would wake up the dead.

Esta alarma es super fácil de instalar, se pega muy bien a la superficie. Cumple perfecto su función ya que suena bastante fuerte, se escucha en toda la casa. Además están muy estéticas. La recomiendo al 100%

Love them it is great when l have my grandson at home. I have a pool in my back yard and it stops him from going out the patio door.

Installed these on some classroom doors to keep the students inline . Works great

Excelente!!! Práctico ! Funcional !
