Review: Little but mighty, they will definitely get your attention! - These ARE LOUD!! They definitely get the job done. Easy to use. They are peel and stick; however also come with little screws, so you have options on how to install. The instructions were quite clear and we had them set up in a few minutes. The biggest take away I cannot stress enough, they are loud. The remote lets you adjust the volume though. They are definitely worth it. They also don’t take up a lot of space and aren’t super noticeable where we placed them. We didn’t use the screws and our front door gets a lot of traffic and the peel and stick adhesive has been absolutely fine. I think maybe the only thing people may find to be an issue is possibly with placement. Our back door the frame didn’t allow for a proper alignment, but it was close enough that it still works without issue. The lip of the frame didn’t fit the width of the magnet without knocking it off when the door was opened. We moved it to on the actual door frame and even though it doesn’t line up like the one in the photo (our front door), the magnet is strong enough that it works still. It’s one top left hand side of the door.
Review: Very loud and does the job - Works well so far and very loud but that is what I wanted. Easy to put on my doors. You can turn them off if you have a lot of traffic during the day and only want them activated at night.

### ⭐⭐⭐⭐⭐ Very loud and does the job
*by M***M on November 30, 2025*

Works well so far and very loud but that is what I wanted. Easy to put on my doors. You can turn them off if you have a lot of traffic during the day and only want them activated at night.

### ⭐⭐⭐⭐ Easy Installation, Very Loud
*by R***A on February 2, 2020*

PROS: Easy installation. I installed two alarms on both my doors in about 5 mins. The box included a remote, the host (big white box that goes on door), magnet box (slinder white strip), and 3 adhesive strips. Remote is already programmed to the alarm, so no need to do that. Adhesive strips seem to hold well. Alarm is loud...very loud. Remote is also very sleek looking and resembles the keyless remote to my car. And yes, you can put it on your keychain. CONS: Although I appreciate the loudness when the alarm is in armed mode, it is WAY too loud for just the normal doorbell function which alerts you the door is being opened. I don’t even use this function for that reason. If you have more than one alarm (as I do) you have the ability of pairing one remote to multiple alarms. However, the downfall of this is that whatever mode you put the paired remote on, this mode will apply to any alarms paired to that remote. Just because I want to arm my front door at night doesn’t mean I want to arm the door of my child’s bedroom as well. I just want to be alerted that he is trying to get out of his room (via doorbell mode). After finding this out I had to unpair the remote and repair them with their own individual alarm. Despite the cons, I find the pros outweigh the cons. It’s well priced and seems to be of good quality. Granted I’ve only had it for one day, but so far so good.
