3in1 Alarm - Door Ajar Alarm, Door Chime with Delay, 0/5/10/30/60 Seconds, 2/5 Minutes, Close Door Reminder, 80 to 120 dB, Time Delay Alert When Left Open for Freezer, Home, Shop. (White)

Works perfectly, beeps if kids hold freezer door open for more than 30 seconds...Then will continue to beep periodically for a set amount of time. Volume, sound, and time adjustable.

Easy to install, quality prduct.

As others have said, it doesn't work for wide gaps. So I added a strong magnet to the side of the magnet bar to make it work. Note that the added magnet will only go in a certain spot due to North/South magnetic pole alignments. See picture for best location. Once I did this, it works well for the wide gap of the door seal on our refrigerator.

Perfect for the application I needed. Not sure how often you or your kids leave a door open on your freezer or fridge, but this certainly will remind you to close it if you forget. Two alarms, 3 volume settings and 3 increments of time: 30, 60 and 90 seconds. It has made us jump a few times while getting stuff out of the freezer due to a quick 30 second alarm (maybe 60 seconds would be better). But it has a loud reminder that you better shut that door! Very helpful when the brain gets detracted! Yes, that happens way too often!!! LOL Thanks for reading! Cheers!!

My boyfriend has Alzheimers and I CANNOT get him to keep the sliding glass doors closed (we have cats that I dont want getting outside). These have helped quite a bit. I love that you can set them to go off at different intervals. Easy install and easy enough to rese intervals or turn off when not needed, without having to remove them.For anyone getting these for the same reason, they will only help so much - he will still ignore it somewhat, reasoning "I'll only be a second", but a second is all a crafty kitty needs to zip out a door. 😒 But at least I hear it going off and can either go shut it or at least monitor where the cats are, all the while yelling in my head "shut the door, fartface!" 🥰

Yes, thanks, I needed that! And, yes, in fact, I discovered that I did need three of them!I needed two for my refrigerator in the kitchen and one on my upright freezer in the garage. My refrigerator has French doors with a bottom freezer drawer, so I needed one alarm for the frig doors (it's so easy for me to inadvertently leave one door slightly ajar that it has happened about once a month) and one for the freezer drawer.I initially ordered one of these for my frig and a different Friggi alarm for my freezer (FRIDGGI - Freezer Door Alarm with Delay When Left Open, 60sec, 120sec, 180sec Reminders, Refrigerator and Fridge Door Alarm or Chime, Low/Loud 80dB to 110dB). I'm not totally satisfied with the one I ordered for my freezer (it's not loud enough to hear inside the house, and it takes too long until it alarms) so I've ordered a second one for the upright, one of this type to add to the first. I'm leaving the first one on because it has a different low beeping sound every 10 seconds as a reminder, so I want both alarms on the upright freezer because both serve a different purpose, at least for me. The door to the upright is critical with a lot of 'money' at risk inside if the frozen food were to thaw!I have my current unit on the frig French doors set to Mode C - Alert after 30 seconds, a reminder every 20s, auto stop after 60min or door closed - so it alerts at the 30 second point which is quite short because one often needs more than 30 seconds to decide, but I find it to be a helpful reminder, so I NEVER screw up now!When my two new units arrive, I will set the garage's upright freezer alarm on Mode B - Alert after 10 seconds, a reminder every 15s, auto stop after 30min or door closed - because I want that freezer door shut ASAP (because the cold air empties immediately on an upright freezer unit as compared to a chest freezer or a freezer drawer). I'll set the new alarm for the frig freezer drawer to Mode D - Alert after 60 seconds, a reminder every 30s, auto stop after 120min or door closed - because I often need more time looking inside this drawer and time is not of the essence in a drawer as compared to an upright freezer.Installation was a snap!I left the garage upright door open once and everything thawed out. Refreezing resulted in frozen lumps and a disaster. These alarms are a critical reminder as we too often are in a rush and can easily not quite get a door fully closed --- and may not discover it for hours.

I bought this for my basement freezer.Scenario. You are going to the park. The car is packed you just remember that everything is in the cooler except the meat. You bring the cooler to your freezer, load the meat in and close the freezer door and it doesn't shut all the way. You run out the door. Spend 3 hours at the park and come home to no alarm. No indication anything is wrong. Next thing you know.. that half cow you bought is now unfrozen and your electric bill went up 200$ THANKS FOR NOTHING FRIDDGI What halfwit designed this thing? There should be NO auto off EVER. Who wants an auto off? Which is worse? blowing through a few AAA batteries? or losing 2000$ of meat?"Mode D - Alert after 60 seconds, a reminder every 30s, auto stop after 120min or door closed (Basement, Freezer door...)."

We love these door alarms. They are easy to set up and they're a great value. No more doors drifting open when we thought they were closed!
