I don't know where to post this. Thought others might be interested?
Overland Journal did a test on a bunch of coolers in the fall 2015 issue - Yeti, a bunch of their knock off's and a couple 80 dollar ones from Wally World. Filled with the same amount of ice, were in the sun half day and shade half day, and a six pack of cold ones was taken out and warm six pack replaced once a day, to emulate somewhat of a real world test.
The wally world units -Max Cold and Extreme 50 kept ice for 4 days
The knock off's kept ice for 5 days
The Yeti kept ice for 6 days.
Build quality was mentioned but not factored in.
