I have a blue/white 5 gallon igloo cooler that was given to me by a coworker.
I have no idea where he got it, but it works just fine.
I have done several batches in it and had absolutely no problems, as a matter of fact I have been consistently in the 75% efficiency on last 4 batches.

Do not mistake my kindness for weakness. I am kind to everyone, but when someone is unkind to me, weak is not what you will remember about me.
