That ain't much of a test, inside, at 70 deg. Put it outside in the sunshine all day for five days in 90+ weather and see how it does. I have had every cooler made and the engle-yeti-k2 types do work better in 90+ heat although not as well as they claim. I've saved enough in ice costs over the last 5 years to buy two more. But hey, at least he won't have to chain that Coleman to his Prius.......
Most people I see with yeti's are actually using them in situations where a $25 cooler or even a bag cooler would be a hands down better choice. Like people dragging their small yeti to the tennis courts for a couple of hours.
And a lot of these same people have Drake or Browning stickers on their back glass even though they don't hunt or they did go hunting one time and a diver down plate on the front of their vehicle. They're not a diver either but they did go to the beach on their senior trip.
Can't argue that most folks that have them could get by cheaper. But the "test" was still bogus and I'm in that 1%
