Does anyone have any experience with Downunder coolers? I found a link in an older which cooler to get, and found a couple places that sell them on the internet. I was looking at the: DownUnder T177 Tropical Cooler. It looks to have the same specs (3" lid insulation, 2" walls) as a Yeti / Galaxy, and is more of a cube, which I like. Just seeing if anyone has used these and if it retains ice well.
