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

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.

Very easy to install. It has different timer options and very loud alarm can hear it from across the house if door is left open. Life saver if you have kids!

Used for alarm on front door and a stair gate to give a warning when son opens it. Sounds loud enough easy to set up and fit

We used this item for a fridge, using the following configuration setting (and using the lowest volume): Mode C - Alert after 30 seconds, a reminder every 20s, auto stop after 60min or door closed (Exit, Freezer door...). It works as intended. However, we note that because there is no physical contact involved in the sensor switch, this leaves the possibility that the door could be left very slightly open and the alarm will not be activated as expected.

Great product easy to install. Hardest bit was finding the right programme. Great peace of mind

I bought this alarm to warn me when I leave the fridge door open. Although the alarm function does seem to work, I'm unable to find anywhere to position it because the two components need to be less than a centimetre apart and the fridge door seal prevents this. If there's a simple solution I'll update.

Exactly what was needed after the freezer door was left open one time too many.

So far, so good. I didn't have patience to work out all the modes, but does what I need it to do. Alert me when the fridge is left open. I opted for 10s setting for now.

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

Tal cual descripcion

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

My kids have a terrible habit of leaving the front door open, and I find I’m constantly having to close it. I don’t always catch it right away, so the cat has gotten out a few times. I decided to get this alarm in the hopes that it would promptly notify us if the door is left open. I’m so glad I did it because it works amazingly well! It was very easy to install: I washed and dried the door and frame before applying the double-sided mounting stickers to components, and then the door. I appreciate that there was an extra set of mounting stickers in the box, which would allow me to move the alarm to another location if necessary, or reapply one if it came off. The adhesive is quite strong and I can’t see it coming off unless it were very forcefully dislodged. I have it set to make a chime sound on the lowest volume after 60 seconds. Without fail, it chimes after 60 seconds, and again every 30 seconds until the door is closed. The lower volume is perfect— just loud enough to be audible from the common areas of the house. The higher volume is too loud for everyday use and is better suited for a security alarm. It would have been nice if there were a selection of chime sounds to choose from, but the one it comes with is fine. An unexpected bonus is that the cat doesn’t like the chime sound, and will run away from the door when it goes off! When we go on vacation, I plan to change it to the loud alarm sound, and to go off immediately when the door is opened. I can see many possible uses for this alarm in various locations around the house. For example, I recommended it to a family member whose spouse has dementia, as it would help prevent him from wandering out the front door. To sum up, this alarm is easy to install and works exactly as described. In the spring, I plan on buying another one of these for the patio door because the kids are even worse with leaving that one open! Overall, I’m really happy with this alarm, and feel very comfortable with recommending it. I hope this was helpful.! 😊

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! 🔔🔒
