3-in-1 Alarm - Door Left Open Alarm, Doors Chime with Delay, 0/5/10/30/60 Seconds, 2/5 Minutes, Gate Ajar Alert, 80 to 120 dB, Close Door Reminder for Home, Office, Shop. (White)

Got this door alarm to alert me that door is open, originally for preventing dog from escaping. Alarm goes off after door open for a few seconds. It is not an obnoxious sound but is a persistent sound alert. Easy to install, sticks with included mastic tape. Can be made inactive easily using the switch.

Last mini fridge had a built in door alarm so we knew when the kids accidentally left it open - moved to a new house, bought a new mini fridge that we thought was exactly the same… nope, no door alarm. This item works like a charm! You can set how long it will wait before alerting you (so it doesn’t go off when you’re just getting a drink or filling the fridge) and how loud it is and it even has a few different tones so you can choose the one you like best. Love it!

Bought for my shed and was impressed with the quality and volume. Super easy to install. Love that I could hear it even from the front of my house

Works as described, however I was hoping for something to use on our gate to alert us if it was left open, this is not exactly what I was looking for and ultimately ended up returning it. Loud.

Super easy to install and it works. A little annoying, but if it helps my son close the front door all of the way that would be great. He's the teenager that slams doors, and now I need to replace the door handles. It doesn't pay to replace them if he doesn't close the door properly. If this works long term, I might buy one for the backdoor because he is the reason why 3 of my cats are missing. I haven't tried to adjust the volume, but might. The delay time is perfect too.

This alarm has saved us electricity by alerting that refrigerator door is not closed. The left door of our Samsung French door refrigerator has an additional sealing mechanism attached to it which requires additional force if attempting to close it with swinging it closed instead of pushing it closed. I don't know if all French door units are like this, but ours is. The sound intensity is adjustable but I keep it at mildly annoying so it can be heard in the next room since it delays for a minute before alerting. Had to move refrigerator farther away from wall an inch or two to allow opening one cabinet door above.

Great, this works well and has extra adhesive pads

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.

La solution du problème de congelateur mal fermé. Avec son installation, plus aucun raté de ma part. Le détecteur d'ouverture est précis. Donc même presque fermé, ça sonne

Great - working as advertised and easy to install on my refrigerator door.

Purchased for a fridge whereby people were leaving the door open, then it would ice up and muggins me would have to clean out excess water. Picked this one based on reviews. With some trial and error to position the unit and sensor, it now works very well. I used white tack to fix the 2 parts to the fridge. Surprising how even 1 or 2 mm difference in position could have it alarming, so white tack was a good solution. Spent maybe 20 mins to sort out the alarm I wanted and to position it on the fridge, it has been working well and alarms if the door is left open more that a few millimeters. The alarm volume is good.

Tal cual descripcion

Finalmente il freezer non rimane più aperto accidentalmente facendo scongelare tutto. Messo timer 1 minuto e poi inizia a suonare. Soddisfatta.
