I had a Yeti 45 for about one year. I did not feel that it was worth the money that I spent on it, so, I sold it on Craigslist and got most of my money back. They are built well, I will say that much. However, I have a Coleman Extreme that kept ice just as long when using side by side and opening them about the same every day. I even "prechilled" the Yeti over night before I added cold and frozen food, and it still did not impress me. I could get about 3 days worth of substantial cooling from both coolers in 80-90 degree summer temps and then I felt like I needed more ice. My biggest complaint is that they are much heavier, but then, that is why they are much stronger. So, I think if you need a cooler that will stand up to alot of abuse, or to be used as a standing platform like fisherman use if for, then, get a Yeti type. Otherwise, I think that the 5 or 7 day Coleman and Igloo coolers will keep ice for about as long, at least in my experience.
