DAYTECH Fridge Door Alarm with Delay 1/2/3/4 mins Adjustable Close Windows Reminder 0-120 dB Refrigerator Alert Wireless Door Ajar Chime for Freezer Fridge Home 1 Set White

These fridge/door alarms are fantastic! The installation was quick and simple, and the alarm is impressively loud — perfect for making sure the door stays closed or alerting you when someone opens it. The build quality is solid, and everything worked right out of the box. I’m very happy with the performance and reliability so far. Definitely a great value for the price, and I highly recommend it to anyone looking for an effective alert system.

These things work great. Haven't had them long enough for an opinion on battery duration. The two different alarm sounds are both very clear and can be turned up to very loud. Also, the tape is ridiculously strong. Don't put it in the wrong place first because it's hard to get it back off! Pay attention to the little arrows on the sides of each part. The arrows need to be aligned and facing each other to get proper function.

I no longer throw away spoiled food! my fridge sometimes looks like it's shut but there's a gap and i have found my fridge out of temp many times, tossing all my food. This alarm has already paid for itself. After a couple minutes of being slightly open, the alarm beeps. you can change the volume. it sticks on easily.

surprisingly good. variable loudness is a plus. the alarm unit is a little bulky for something attached the the fridge, but it is not too terribly obvious on top of the door (5 stars if it was smaller). it was easy to install with the removable adhesive strips, and i was happy to discover it worked reliably even with a larger gap than recommended. my fridge has a large thick gasket so i was concerned it wouldnt work, but it does.

This was a waste of money. It worked okay for a couple of days. Now the alarm goes off when the door is fully closed. Opening and closing the door used to help but now it doesn’t. Turning it off then back on again doesn’t help either.

Great little gadget. Installation was easy, a great easy way to let us know that the small fridge was left open. The option of different timing works great, the sound is loud enough that i can hear it from downstairs if someone has forgotten to close it, but not too loud that it scares our dog. The adhesive provided stuck to the fridge well.

The product had no instructions, so I would not recommend buying this brand.

So far so good, but I just had them a day. I had some issues with it going off when the door was shut, but I think you just have to play around with the sensor and move them closer. Video shows it going off when door opened. Pretty cool. Hope it does the job. Update: They work great! Lifesaver!
