Fridge Door Alarm with 60 Second Delay, 2, 3, and 4 Minute Reminders, Loud Chime or Siren, Refrigerator Door Ajar Alarm, 4 Minute Reminders – Small Size. (Grey)

We just found our freezer door open the other day and everything was starting to thaw. Thankfully, we didn’t lose everything. I immediately looked for an alarm and found this one. So far far, this is a fantastic little alarm. Very loud sound if you leave the freezer door open for for any long amount of time. No more worries about leaving the door open. Would highly recommend getting one of these if you’re freezer has the ability to be left open and no alarm built-in. Save yourself hundreds of dollars and ruined food. You won’t be sorry.

Discrete beeps have reminded family member to make sure refrigerator door is close. Cold be a little louder but does the job. Easy to install.

Easy to install and smaller than I thought, but works great. Wife opened freezer which backs up to our bathroom. I could hear it through the wall.

Worked well. I have a pull out freezer bottom and the gap works. Pro- med level is good volume for a small house, increases noise levels at every few min or so. Con: beep are intermittent and lower level volume at first, may be confusing on what the sound is. Also beeps lightly at EVERY opening

I liked it, easy to install and use.

Excellent item. It saved me from having the door left open on the refrigerator all night long costing me A lot of melted items. Don't have kids...lol

This thing is LOUD...when it reaches it's apex. Those who say it is NOT probably don't understand what this product is for. What this is NOT: An alarm that loudly goes off whenever the door is opened. What this product IS: An alarm that goes off AFTER AN INITIAL TIME PERIOD to let you know the door is ajar/open. In other words it is NOT a alarm to prevent people from opening a fridge and stealing your prized piece of cake. Thank God (or the engineers) it is not. That would drive me crazy to hear a loud noise every time the fridge is opened. It works like this...when you open the door, a VERY QUIET, almost imperceptible beep sounds. It keeps going off quietly like this every 6 seconds. But the excitement builds. After a minute has passed a brief LOUD beep sounds. Oh I'm feeling it now! But we are just starting! The loud beep keeps happening every minute! Oh the joy! The anticipation keeps building and after three minutes pass a LOUD CONTINUOUS BEEP occurs! Please don't stop now! Keep going, keep going! After 4 minutes the loud continuous beep reaches its climatic crescendo and becomes a SUPER LOUD continuous beep. Ok stop stop stop I'm done...I need to catch my breath. So you close the door to turn it off or slide the switch on the side. And abandon the fridge to go back to your own bed alone so you can sleep. Did I tell you there are 4 loudness settings as well? And you can simply turn it off if you are going to clean your fridge at it will take longer than a few minutes.

Someone accidentally left the freezer open so I bought this hoping to prevent future incidents. Very loud, which is helpful because the freezer is in the garage. The instructions show it can only be used on certain types of fridges and freezers, the split combos normally don't work but if you can open it from the sides it's suppose to work with this. Very simple so I appreciate it doesn't need bluetooth and all the other fancy requirements like some alarms.

Excellent device...easy to install ...precise and not expensive.....less headache with mother in law with bad habit opening the fridge door for indefinite time ....

After yet another freezer-not-being-properly-closed-by-returning-offspring-after-a-nightout, we got this device. I had previously had a more expensive wireless temperature monitor for the same purpose, that was really designed for professional settings like labs etc. It had 2 sensors you just put in the freezer/fridge and then a receiver/alarm unit located within range. But I found it went off occasionally for random temp fluctuations not actually caused by the door being left open, and was then fiddly to reset. Anyway I made the mistake of thinking 'those days are over now the kids are older/more responsible....' - well, you know how that one ends. A week ago we lost another load of frozen food after an all-night door slightly ajar situation which caused the tempertaure to rise so much, we had to defrost the freezer completely and start it again (BTW top tip - last time this happened, we thought something had gone wrong as it simply wouldn't reach freeze temperatures again. Paid £250 for a Miele callout to be told 'defrost it completely, then turn it on again, and leave it for 12 hours'. So that's what we did this time, without paying for the advice - works perfectly). So now I've replaced my old temperature sensor with this distance monitor. So - as for installation - this is the tricky part, and of course it all depends on how your freezer is located and whether it's built in or not. So ours is built in and I decided the neatest solution would be to position the device on the underside of the door - see pic. The main unit went on fine - luckily there was a 4cm gap between the back edge of the door of the freezer, and the vertical panel between the door bottom and the floor. The sticky pad for the main unit worked fine also - very sticky and am confident it will stay on for a while, despite being at maximum risk (ie with gravity applying constant pressure and in an area exponse to damp/cold). That said, I only needed to apply it once - see below. The instructions were that kind of non-English, minimal type you get from, presumably, Far East manufacturers, but it's fairly easy to work out that the different volumes of alarm are activated by 1, 2, 3 or 4 presses of the 'set' button. The next bit was the hardest part. I wanted to position the smaller 'activator' unit so that even if the door was only slightly ajar, it would go off. So here's what I found: 1. The alarm triggering depends not only on how close the units are to each other in terms of the gap between them side-by-side, but also 'vertically'. So you can see from the pic how I ended up with the smaller unit moved towards the 'top' of the main unit. I found this to be the exact right spot for triggering even a slight gap (say, 1cm or less) of the door being ajar. This is crucial for us as it only takes this kind of gap, left open all night, for the freezer to get upset. 2. The sticky pad for the smaller unit stopped working after 3-4 efforts to get the positioning just right - presumably because I was sticking and unsticking it to a slightly greasy, cold, aluminium surface. Cleaning the surface didn't help, so I gave up on the pad. I took it off from the unit and instead improvised with insulating tape and UHU glue. I also marked the final location with a Sharpie, as you can see in the pic, for good measure, in case it gets knocked off. 3. My wife is very sensitive to noise, but we also need the alarm on the loudest setting, so we can hear it when we're in bed late at night, as that's when certain people seem to visit the freezer carelessly. So it will be interesting to see what happens if we are opening the freezer to load/unload and the louder alarm is triggered (think this is 2 or 3 minutes, but again neither the instructions or the page here is particularly clear on this point). However - I can confirm - it's very loud and you should be able to hear it anywhere. 4. Finally, just to note, to replace the batteries you apply a bit of pressure to the front of the main unit and push it 'upwards' (towards the logo end), and the cover should just slip off. I can do this even when its located under the door like this - not difficult. Hope that's all helpful! Will repost an update if it goes wrong/doesn't last long.

accurate with even a slight gap in the refrigerator door, very happy with the product,

Une fois qu’on prend le temps d’attendre les minutes indiquées dans le mode d’emploi, c’est très efficace

Mi nevera tiene un sensor que apaga la luz cuando detecta que la puerta está cerrada y además emite un pitido cuando lleva más de un minuto detectando que está abierta. El problema es que el sensor detecta que la puerta está cerrada cuando realmente no lo está y falta un centímetro para estarlo. Total que en varias ocasiones me la he dejado abierta y al confiar en el pitido pues pensaba que estaba todo bien, y no ha sido hasta la hora, las dos horas, o toda la noche que me he dado cuenta de que había quedado abierta. Decidí probar este dispositivo que con paciencia y colocándolo cuidadosamente es capaz de detectar si la puerta se queda abierta un solo milímetro. El sonido que emite es muy fuerte, puedes elegir cada cuanto quieres que pite y la intensidad (tiene 3 intensidades y 3 modos de pitido). Además, la pila parece que va a durar. Y lo mas importante es que cumple su función, desde que lo tengo puesto no he dejado nunca la puerta abierta. Por último, el adeshivo que trae es muy fuerte, no lo pegues hasta que no estes seguro de que está a la distancia que necesitas!
