Yeti fan here. Yeah they are expensive, but I buy quality coolers so seldom so it's not the top concern. Value is.
What sold me was a trip to Lake Don Pedro in CA. We where camping for 5 days. We took a Coleman and a Yeti 65. We pre-cooled the yeti and I filled it with home made ice blocks. After 5 days we had to chip the bacon out of the ice it was so cold. It blew my mind. The combination of pre-cooling, opening just for meals, and the yeti design worked amazingly.
Could we have done that with a Coleman? Probably.
The yeti has been bomb proof, and it's one of our most beloved pieces of camping kit. I purchased a soft side for the boat as well. They work great for beer because you open them so often, but the zipper retains coolness as you fetch a beer. Anyways, huge fan of yeti.
