@bobco, I've never had a cooler hold ice as long as a Yeti does. And I don't think I am alone. I've read reviews on all of those types of coolers, and yours is one of the very few that I have ever seen that was negative.
And when people buy them, they hardly ever end up selling. If you search Denver's craigslist right now, there are 8 coolers listed under "YETI". If you just search cooler, you will get hundreds of hits.
They certainly aren't for everyone. And if I only did day trips I wouldn't buy one. But IMO, they are well worth the cost to me when I spend time at Powell where ice is $5/bag and hours (round trip) away.
I am not discounting your experience, but perhaps you got a bad one?
