I have several yeti's also, 20,45, 65 , they all do very well keeping items cold and holding ice for several days.
I've never used them, but a lot of folks here in Louisiana swear by K2 coolers also.
Reference: Good Guy :
Just did a trade with "brushout" on a remington bbl action, condition was as stated and very fast on shipping
No problems with the transaction. A+++
