Seven months of ownership into my Yeti. Still a big fan.
I wish I had returned it and upgraded to a larger one when I bought it though.
Some real world tests: I had both the small 20 quart Yeti and my FIL's 35-40 quart Coleman in use this weekend--both were holding beer and pop only, other than for 4 hours when they were holding some frozen food. All the frozen food remained frozen, as expected with just about any cooler.
The Yeti kept the ice longer, but for real world practicality they both were perfectly fine for a long weekend. I replaced the ice in both one time--keep in mind that neither were kept in the shade, and bother were opened frequently. The big differences that I noticed in the Yeti and the "normal" Coleman:
- Yeti was too small, really. I'd have liked a larger version.
- Yeti is quite heavy. Not an issue for me.
- Coleman did just fine, but it leaks a little bit, and you have to be careful opening it or the hinges would break after a few years.
Also, everyone here should look up SHITI coolers. Good stuff.
