    I bought this alarm to use on my refrigerator, but I ended up using it on my shared entrance door instead. My neighbor often forgets to close the door, and it’s very cold outside. This alarm warns me if the door is left open, so the entrance doesn’t get freezing cold. Works perfectly for this purpose!

    Excellent for signaling a poorly closed fridge door. There is a led that flash, then a sound after 60 sec. It takes a small space between the fridge door and the structure (1cm).

    Easy to install, convenient to use. And the alarm and magnet must be glued along the edge of the door. The slightest gap gives a trigger, which is indicated by the frequent flashing of the LED. A minute after the trigger, an intermittent not too loud signal appears, which is required in this case. I think the battery that comes with is not enough for a year.

    The title is misleading. "3/15/30/60 Seconds Adjustable Delay" is not mentioned neither in original paper manual nor on the page, and I still don't know how to make the delay shorter. Minus one star for that. Also I don't like those short LED flashes every ~5s that indicate "I'm alive", they surely reduce the battery life; one could just open the door when in doubt whether the device is alive.

    Everything works great! Thank you. Until I figured out how to change the delay from 60 seconds to 30.

    The product is as described and works very well. Very easy to install. The only reason i gave 4 stars and not 5 is because there is no way to set the length of time before the items starts to bip. You need to wait 60 seconds and i found no way to change it. The description says 3/15/30/60 Seconds Adjustable Delay Refrigerator Alarms Wireless but I found nothing about this in the documentation that came with it

    It works very well and does exactly what it's supposed to. The only issue is with the instructions, which mention that there should be less than 1 cm of space between the two components to avoid triggering the alarm. I'm not entirely sure if it's because I had to install it upside down or if this is just how it works, but I found I needed to leave more than 2cm space for it to be able to detect a little gap. Overall, it’s a great product, just test it before stick it definitely. One photo with alarm off and other with alarm triggered.

    Space slightly more than 1 cm to achieve best results. You will want the alarm to go off with every little opening of the fridge door. So space it as far apart as possible. Seems to work ok so far.
