Product review (1 stars): A complete waste of money
A rip-off, unless maybe your freezer is in your bedroom. The so-called alarm is a little feeble peep which sounds every minute. My three freezers are in the basement, and the peep would never be heard elsewhere in the house. Also, the visual temperature displays are all stuck on the same numbers they arrived with -- go figure. A complete waste of money, but how does one go about getting a refund from China? Chalk it up to experience and move on. The only reason I bought these alarms on the Internet was because I have not been able to find any in stores.
