I tested the KoolerCap using a 44-quart cooler, that I've had for about 15-years. For each test I placed twelve canned sodas from my refrigerator into the cooler. On top of, and around the sodas I placed the listed amounts of crushed ice that I purchased from a local supermarket.

 

After about 24-hours into each test I began to check the melting progress of the ice every few hours, to simulate the opening and closing of an ice chest on a camping or travel trip.

 

Using 9 pounds of ice, the KoolerCap extended the ice life by almost 29 percent.

 

Using 20 pounds of ice, the KoolerCap extended the ice life by just over 30 percent.
