Okay Except Battery. These actually did the job and are very loud but the battery does not last over 12 months. 2 months since installed and 2 are already chirping for the battery to be changed. Smh
Don’t be alarmed. These little things pack a wallop of sound when triggered. I placed a bunch of them on all the doors leading out to our swimming pool for safety reasons if there are little ones over at the house. The double as intrusion alarms as well when I arm them at night. They are super easy to install and a good lithium ion battery will last a very long time in these. I highly recommend these.

needs to be reset EVERY time so will replace with another option. I care for a young man with autism that might wander at night. The chime “door bell” mode would be fine but the VERY loud shrill alarm is the default and it needs resetting to the chime mode every time he opens his door and then he is subjected to the shriek siren. No good for what I need.
Sticker sucks. It constantly keeps falling. I had to use a different tape to stay in place
Passed inspection. We purchased these to put on our exterior doors as required by the city when you have a pool installed. The one on the slider sits very closely but the standard exterior door has a (decorative) recessed gap between the frame and the edge of the door of a full ¼” – I didn’t think it would work there, but it has no problem with the gap. They work exactly as described and passed inspection without issue 🙂

Nice Alarm for Garage Freezer. I wanted something to alert me if the garage freezer came open. These do the trick. Just remember to turn it off before opening the door, and on after you close it.
Easy to install work great. These work very nice
Hate them. I thought I ordered alerts, it’s so loud.
Really LOUD. Easy to install and use, just decided not to use for my purpose which was to sound a reminder alarm for my kids and nieces and nephews to close the door during the summer. Waaaay too loud!

Very loud. Works well but doesn’t stick well
They do their job. Loud AF. They do what they are supposed to, easy to put up. Good product.
Great price for product. Great price for two window alarms, just what I wanted. Be warned they are very loud. Only time will tell how long they last, these are replacing ones about 10 years old.
