They look very nice, but cost more than the first 3 cars I owned (combined!!!). Not sure that I really need a military grade (and priced) ice chest.
I have had good experience with the
better Igloo and Coleman coolers - these are typically the larger sizes. The hinges on some of the cheaper coolers go after a bit (replaceable or ignorable), and I have had some drain plugs leak after while (silicone caulk fixes that). When they 'die' they still have life as tool chests, chainsaw cases, etc.

If you really need extended time, consider locating a source for dry ice where you live, work, or play.
