Product largely delivers on its promises. However, a couple points render it almost ineffective.

The suction cup will not work in freezing temperatures, and quickly loses its grip. And most annoyingly, the freezer alarm will sound if the freezer gets "too" cold!

I had planned on using the device to sound an alarm if the chest freezer in my garage failed. But the alarm keeps sounding, telling me that my freezer is too cold!!! I happen to be glad that my freezer is at or below zero. I wanted an alarm that would tell me if the freezer failed. Not that my freezer was too cold. Ridiculous.

Installed the Freezer/Refrigerator Alarm/Thermometer on an old (30+ years) upright freezer without self-defrost feature. Amazingly enough, the sensor wire would not allow the door gasket to seal fully around it and when the freezer door was opened and then closed the rapid cooling of the warm air inside created a partial vacuum which was pulling warm, humid air in around the sensor wire. This resulted in a very quick accumulation of ice/frost on the upper cooling coils. Solution: drill a 3/8" hole through the side of the freezer, insert sensor through to the inside and mount securely, completely fill hole around wire with silicone caulk from inside-out. Problem solved. The sides of most freezers are nothing but a 2-inch wall of foam insulation with steel/plastic coverings inside and out. The modified arrangement solved the problem with premature and rapid frost buildup. This might not be a problem on more modern freezers having a self-defrosting feature.

That said, the thermometer is accurate to within 1 degree plus or minus and it works exactly as I hoped it would. The only solution to avoid this would be some kind of flat sensor wire but I suspect this is not a problem for more modern frost-free freezers.

I purchased this for a freezer we have in our basement. While the thermometer works just as advertised, I find that the alarm isn't loud enough to be heard upstairs. I'll be keeping it, and hoping the freezer never goes out.

Not a bad alarm however it seems to be impossible to set the temperature range it affects.

My freezer is rather old and runs at -9F, while the sensor goes off at any temperature above -11F.

While the unit does monitor the Temp for Freezer or Refrigerator, the volume of the alarm is surprisingly soft. My wrist watch alarm is louder than this thing. If you want to monitor your Freezer Temp in the kitchen or someplace where you walk by every day, this unit is OK. If you have your Freezer in the basement or garage where you need an audible alarm to warn you of a melt down this unit is not for you.

I ordered 3 of these for 2 freezers and my refrigerator freezer. They have worked great and give me peace of mind.

When I placed this item in the freezer it wouldn't stick to the side of the freezer as it should. But I expected that from reading the previous reviews and it wasn't that big of a deal. The problem is that the alarm would not shut off regardless of the temperature set. A previous review said the freezer had to be below 9 degrees below zero but I set it for 0, -5, and -15 degrees below zero and the alarm would still not stop. The company was very accommodating about returning the item for a refund.

The quality of the items are very poor. We used to use them on the fridges and freezer but found that they were beeping all the time . Currently we are still using 1 but even that one is on its last legs
