[Elbert Chamblee]

$40 VS $10.... Chilled both with ice and dumped out. Filled both with ice and put on golf cart on patio overnight. Next day about noon took both cups inside and tried not to shake either cup. Inserted my temp probe I insert in my bbq cookouts. Used the same probe on each measurement. Water temps yett-33.8 & 34.1. Walmart Ozarka 35* & 35.4. I used the same probe and 2 different head units. Our Walmart here received 160 last week and sold out in 2 days. So I guess the secret is out.
