Product review (5 stars): New Kitchen Staple
I have food allergies so end up cooking many meals then freezing theme.  It's important to me that my food stays at the right temperature.  My freezer door is not consistently sealing, so I needed a product to let me know my food was still safe to eat if it had one of its defrosting eposides.  Along came Freezer Meter!  It was easy to install in my freezer and gives me the piece of mind to know that my freezer is working.  This is a low cost product that is a new kitchen staple.
