This saved my stash when we forgot our deep freezer open in the basement. We had the alarm on the side of our fridge in the kitchen and heard it going off.

I’m sorry you lost so much. It’s so draining pumping at work just to have it go to waste :(

There are freezer alarms for this. We accidentally left ours open once and the alarm saved my stash.

I know it doesn’t bring back the milk you lost, but it’s worth buying for the future.

Here’s the one we have if you’re interested.
