These were very easy to install and very loud. I would recommend them in a child's room (window) or entry door. If using them for a pool alarm/inspection, they won't pass. They do not want an alarm that is switched off by a remote. That is the only reason I'm giving this four stars. Otherwise, it is a good product.

This alarm is crazy loud. Bought this for invasive house guests, ikr. Set up was easy using the video from the ad and the supplied double sided adhesive pads; it took less than 5 minutes. Love the remote control, only have 1 alarm setup/programmed. All the modes are loud even the door chime. I like that it does work just wish there was not a loud audible beeping sound when its armed. Half the time I forget its on and enter the room and scare the bajesus out of myself. I recommend this as an…

Really not much to add about this little device. Super easy to setup/install and best of all, it worked just like they said it would. Great value for the price paid.

I purchased these to add to my front and back doors. My son is autistic and eloper risk. These are very loud and gives peace of mind.

Wsdcam makes them good. Been using this model for like 3 years now in every apartment I've had. Price is very fair. The alarm is just like a car alarm, local, which means police aren't automatically dispatched when it goes off. But it is VERY loud, would definitely scare off your average crook. Best money I ever spent on these.

I've only open and installed one so far, but the one that I've already open is exactly what I expected PERFECT. Its loud which is great since my bedroom is kinda far from the back door. A plus is I can set the alarm from my bedroom. The installment was very easy. Batties was already in the alarm ready to go remotes were already programmed which was a plus.

Used these alarms on the inside of my doors of my enclosed trailer. The Remote works well and the alert is pretty loud even being outside when activated.

Awesome alarm i feel safe having this device and I’m buying a rental property where I will buy install for each unit. I will buy more in the future

The installation could not be simpler. Just drop in the batteries (included), affix the sensor, and then affix the alarm itself aligning it to the arrow of the sensor (and itself).As others have noted, each remote is preset to control both alarms simultaneously. If you want independent operation, you need to reprogram the remotes.The alarm is loud as heck. The 'ding-dong' chime is just as loud. I have seen someone in one of the reviews complaining about the loudness, and in a small house or…

It is loud and I love it. I use it because my daughter is a sleep walker and it brings us great peace of mind. May not have a long lifespan, requiring frequent replacements.

Installed in less than 5 minutes. Remote is very cool, you can set and disarm from outside. And the sound, LOUD. Great buy.

The alarm is easy to install, loud, and does it's thing when you open the door. However, it also makes loud beeps while arming or disarming. I wish these could be done silently. I don't want to notify my neighbors when I'm heading out or arriving back. Might have to return because of this. Too bad, because everything else works fine.

I bought this because people are getting poor due to no work from COVID. Try to protect my home. The alarm works well and loudness is okay. remote control works well. will suggest this to friends.

I am now deaf after being startled awake at 6am by these things screaming when my daughter forgot they were there and went to let the dog out. No one and I do mean no one will sleep through these except for me now.

Incredibly happy with these. Half the Chinese junk on Revain doesn't work as advertised. This is one exception that actually does.What I love most? Once these alarms go off, you can't just close the door to silence them. You need the secret remote to do that ;)

Just what we needed for final inspection by the County for our pool. Sounds off very loud! Could be used for general security for those without a monitoring service.

It's pretty loud and we have neighbors who watch out for their neighbors property. I keep things pretty secure (cameras and things) but this alarm added to our front and back doors is a good additional measure

Nothing to assemble, and setup instructions are pretty straightforward.Two sirens going off at the same time can get the attention of anyone a few hundred feet away; they are pretty loud. One control device can be used for both alarms although I find that controlling both can be tricky.Update: After six months, batteries signaled low power. After battery change on one of them, alarm goes off unstoppable. Makes me wonder, is there a problem that is endemic to the alarm unit or is it possible…

I put them on our tractor and on my shop doors as a neighbor had their out buildings broken into while they were home! These are so loud that we couldn’t miss the noise even if we were on the other side of our property. Along with the cameras we already had, but use to turn off when we were home, We also put removed speaker apple tags on several items so if things are stolen we can track them. I’m sick of the crime happening in our rural area. We work too hard for people to just drive by and…

Used in my school library to alert to students leaving through the back door. Easy to install, good loud sound, works for over a year on the same battery, easy to activate or un-activate. I got two for about 15.00 , a bargain.
