Dont forget to throw Engel in the mix...I have no problem keeping ice or fish in my cheap marine Igloo...Like others have said its the hardware that sucks...Fill up a 55qt igloo with a couple limits of fish and ice and then lift it up...those handles will come right off after a couple times doing that. The latch that holds the lid shut will break after a few fishing trips also...They do make steel hinges and latches to replace the cheapo ones but they are also pricey for cooler parts..
I'll keep using mine for now b/c its lightweight and its working for me right now...but I've been thinking about getting a k2..support local and have a cooler that matches the boat. Problem is weight for me though...maybe I should lose a few lbs to fix that
