Added security
I live along a busy street / walkway. Being single & disabled, security & safety are very important. I got this twin pack of door alarms for added safety. The cost was good and Phillips has a good reputation.The alarms were simple to install. The two alert options are great. The door alarm chime is LOUD but has a pleasant ding ding sound (imagine the alarm sound at a small boutique, etc). The safety alert is a loud, screaming sound that would scare anyone away.Easy to install, choice of sounds and good value.

Loud but not overly.
120 db is an interesting intensity to use. It is loud but a few feet away it doesn’t seem all that intense. If the house is quiet it will be heard. My wife has Alzheimer’s and wanders. I want to know if she opens the slider. Works perfectly

Affordable safety device
This thing is so loud for such a small device. It can also be used as a door chime. Extremely easy to set up. Added safety and a great deterrent for a small cost.

Could be better
Ok, 3 stars because the price it’s reasonable, the quality seems to be good, and installation is easy, 2 stars less because it’s a tool for security and as you can see in the video is very easy to disarm the alarm all you have to do is close the door or the window and it will go muted again, the least that i was expecting was once the alarm was on and the person would have to reach button and switch it to off, but all you and the thieves have to do is close quickly and the alarm will go back to silent 😒

Great inexpensive security device
Purchased these for my back screen porch door. It works well and gives me a peace of mind. The price was real good for the 4 of them. They were super easy to install and the adhesive on the back of them stick really good. Definitely would recommend this for budget friendly security!

These are great ! Mounted perfectly onto my doors and work very well. The sound is very loud and definitely alarming even when it is just on the chime mode. Definitely a great purchase at a great price point.

The dollar-to-value ratio on this goes crazy. Never thought something so cheap could bring this level of comfort.The product:These were easy to install (less than 5 mins with no tools) and function very well.When they said these were loud, they aren’t kidding! Easily audible throughout our house.

Easy to install. Works well apart from one of them. One seems to be not working well. Pretty disappointed.
