Auto-defrost refrigerators/freezers cycle their temperature between 0 degrees F and above 25 degrees F. Unfortunately, this alarm doesn't accomodate the cycle resulting in false alarms. The owners manual offers a cop-out solution, "wrap the sensor in foam". OK -- so how does one calibrate the sensor and know that it is set properly? It would take a lot of trial an error, adding foam, removing foam . . . who has time for that? It needs a switch where the consumer can pick the alarm temperature.

Like the title reads, this works great for a top load freezer. When the fuse tripped in our basement we lost a lot of food when we discovered the mess five days later. I bought this and the next time the fuse tripped, it was only a matter of hours, not days. Sounds like a cheap bedside LED alarm clock beeping, irritating and loud enough to make you wonder what's going on. So I bought one for the garage fridge/freezer combo which we use in the summer. This did not work out as well, since it's gone off a few times when the power was fine to the garage unit. SO I would only recommend this for a top loader freezer that doesn't cycle as much as a smaller kitchen model. It has a set cold limit and it not programmable. But it's cheap and effective in most cases. If you're a hunter and store lots of meat in your freezer, this is a worthwhile investment.

I purchased the alarm because my kids were always leaving the freezer door open resulting in defrosted popsicles, ice cream, meat, and the like. I bought the alarm and installed it as directed after spending a day defrosting the large, upright freezer. (Both my husband and I are engineers, so you can be certain we followed the directions to a "T".) To my surprise, two days later the freezer door was open, frost had built up on the metal shelves, and NO ALARM WAS GOING OFF! I pulled the alarm off the instructed location and put it outside the freezer to see if maybe the batteries were bad. No, the alarm sounded. DO NOT BUY THIS! We now have to defrost the freezer for the second time in a week. I plan to return this worthless device.

This was just the type device I wanted so I will be warned if the basement GFI kicks out and my freezer gets too warm. I just purchased $800 worth of products and it would be a tragedy if it all thawed. The alarm sound is noticable on the first floor but only if background noise (TVs, etc.)is low. This simple unit is worth the cost.

We purchased this device for the same reason most everyone else did, they already lost food. The device didn't like our defrost cycle so I put bubble wrap around the sensor (as in the directions) and it still didn't solve the problem. I then moved the sensor toward the lower part of the freezer (uprightstyly) compartment and now it works fine. We placed the alarm part near our cold air return and so can hear the alarm through our duct work. Another option for those complaning about the freezer sounder being to soft in volume, hook up a baby monitor and you can hear the alarm anywhere the baby monitor can transmit. Ye ha
