Does your current cooler have any limitations?
In my experience, it didn't keep stuff any cooler any longer than my cheap coolers. I can go about 4 days with my cheapie igloo cooler and some dry ice before it all turns to water. The same thing was true for the Yeti. However, I'm hardly ever out for 5 days straight without refuling, and if I refuel I can get more ice. And the Yeti didn't buy me an extra day or two of cold food like I thought it would. If I were regularly gone for more than 5 days at a time, I would get an ARB fridge.
The Yeti was truly a case of good marketing and me being excited enough for gear to try to justify a need that didn't exist. And on top of that, I didn't see any true benefit for keeping my food cold. However, the Yeti is built like a tank and I have no doubt it'd survive a bear encounter. But I've never lost a cooler to a bear so that's another need that didn't exist.
