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

This alarm was easy to set up. It works perfectly and is helpful when the grandchildren forget to close the door. I like that it has options for timing. I was not able to use it, however, on the intended door, since the trim around the door is not flat and it would not attach properly.

Exactly what you are looking for. Different volumes and alarming modes. Suits all the needs of a battery powered independent open alarm. Works as described.

Simple, easy to use and install and it works as advertised. My garage is separate to the house. I have video cameras and signage but I wanted an aural alarm to deter a bad guy (By the way, this unit does NOT connect to any wireless network. I knew that when I bought it and don't need that. Just wanted to let you know.). I chose the 5 second delay and the loudest alarm and it is very loud. I don't think a crook will hang around very long with that going off. Anyway, it works great and does everything I expected it to do. I would buy this again.

Needed this for my freezer since my family tends to leave the door open. It works great. You can set it to different modes and sound levels. The only reason for giving it 4 stars instead of 5 is that the settings are a bit confusing but once you understand them it’s not bad. Overall good value and recommend.

Works good

NOT A GOOD FIT FOR ANY FRIDGE as every fridge door has a rubber seal to prevent leakage of cold air. Here's why.... If larger sensor and the smaller sensor align to the edge of the fridge body and to the edge of the fridge door respectively, i.e., if their seperation is equal to the thickness of the rubber seal, the gap sensor doesn't work. So I had do the following: I had to stick only one half of the large sensor (with the orange round) vertically on the fridge body. The other (unstuck and overhanding) half of the large sensor sticks out over the rubber seal - i.e., the large sensor is not fully stuck to the fridge body. The mating smaller sensor went perfectly on the side of the fridge door as it is slim and small. I wish the seller provided an adapter plate that can be stuck to the fridge body, and the larger sensor could slide on it for adjusting the gap vis-a-vis the rubber seal thickness. Tge designer can use my suggestion, I hope.

Bought this because my son kept leaving the bathroom door open and the dog kept drinking out of the toilet. Leave the door open the alarm goes off you remember to shut the door worked perfect perfectly.

Saved us a couple grocery bills worth of food! My son kept leaving garage fridge open by accident in new house and this saved us. You can set the alarm with different timed settings to constantly beep when not closed, or after 1,2,5,10 etc minutes. It beeps as soon as you open too to remind you oh yeah we have an alarm on it, close the darn fridge!

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

Der 3in1 Alarm mit Zeitverzögerung hat mich absolut überzeugt. Er vereint mehrere Funktionen in einem kompakten Gerät und sorgt für ein deutlich sichereres Gefühl – egal ob zu Hause, im Büro oder im Ferienhaus. Ich benutze es an der Haustür damit die Kinder nicht vergessen diese wieder zu schließen. Besonders praktisch finde ich die einstellbare Zeitverzögerung. Man hat genug Zeit, den Raum zu verlassen oder den Alarm zu deaktivieren, bevor er auslöst. Das macht die Nutzung sehr komfortabel und verhindert unnötige Fehlalarme. Gleichzeitig reagiert der Sensor zuverlässig, sobald eine Tür oder ein Fenster geöffnet wird. Die Lautstärke des Alarms ist beeindruckend – deutlich hörbar und abschreckend. Genau so soll es sein! Auch die Montage ist kinderleicht und ohne Bohren möglich. Einfach anbringen, einstellen, fertig. Die Verarbeitung wirkt hochwertig und stabil. Trotz der kompakten Größe bietet das Gerät eine starke Leistung. Ideal für zusätzliche Sicherheit – besonders auch auf Reisen oder in Mietwohnungen. Insgesamt ein durchdachtes, effektives Sicherheitstool mit sehr gutem Preis-Leistungs-Verhältnis. Klare Kaufempfehlung für alle, die unkompliziert mehr Schutz möchten! 🔔🔒
