I'm testing the new esky.
Using some frozen salt water and other home made ice bricks, packed it full of beer and coke and threw the thermo in to suss it out. Most of the drinks went in cold, but i did throw in a six pack that was warm.
We're gunna open it 10 or 15 times a day to try to get a true reading.
As we keep the esky in the tent itself when camping, i've put it in the garage, hoping that bit of temp from parking the car in there will be compatable... maybe....
Within 1/2 an hour, recording -4 degrees.
Lets see if it really does 10 to 15 days huh.
