Did not work for my freezer
This is a really great idea; unfortunately, the product did not work with my freezer. I have below zero temps in my freezer, but the indicator never fully froze. Save your money and buy a freezer thermometer.

I always wondered if my food was safe after coming home and seeing the clocks flashing. This tells me how warm it got in the freezer. I read the review about the blue liquid not freezing that simply means the freezer isn't below 0. Remember that the manufacturer is ultra conservative about the temperature. So no worries about the blue liquid.

Can't even get it to freeze all the way
I bought this to put in my freezer as I tend to travel and have had power outages (flashing clock when I've gotten home) while away. This looked promising. However, after a full 2 weeks in my freezer (temperature well below freezing) the blue section of this gadget won't freeze --- thus I will never know if my food is spoiled beyond 14 days. The instructions say that the whole block will freeze after 48 hours --- this simply is not the case. This makes the gadget somewhat unusable. Thus I cannot say I would recommend to others...

We have lost power a few times and often wondered if our freezer food was still good. We are hoping this item will help us make an informed decision. I'm sure its not perfect but it will allow us to know about how cold the freezer was and the likelihood of spoilage. It has not been put to use yet so I can give it 5 stars.
