Now that my eye has stopped twitching...
I'm not a fan of the ostentatious cooler but if it does the job better, I'm all for it.
I own - or have owned - cooler options from Strong Bags (two diferent ones), Aerocoast, LuggageWorks and Travel Pro. I also have a Brightline but I'm retiring that from service.
All of them have their pros and cons, but with the exception of the SB Summit, none of them really insulate as well as they could. The SB Summit is pretty good for cooling, but that's because it ends up double-insulated and its capacity isn't as good as the others.
I'm one of those knuckleheads who tries (the operative word is tries) to pack 4 meals a day into a cooler. I put a lot of work and care into it and while I've accepted the constant hassle of replenishing ice bags, a little more capacity with better insulation would be really, really nice.
So while I agree that the Yetis don't necessarily look the part, if they work well, I'd be willing to give one a go.
EDIT - Jesus Christ those things are expensive. I'd be willing to give one a go if someone else paid for it.
