Bests & Worsts Reviews from Amazon

I bought this alarm 6 months ago to protect my frozen breast milk stash. I heard too many horror stories of people losing their stash. I just opened the freezer to pull a bag of milk and it’s melted. I don’t know when we lost power to the freezer but the alarm did not go off. Maybe I shouldn’t have relied on the alarm but I thought that was the purpose. When I realized the milk was defrosted, I checked the app and the last time it checked the freezer temp was 2 months ago!!!! I don’t think this is is how it’s supposed to work.
