have you found out anything else about the cooler because while on leave in florida i found one on the side of the road which i claimed for my self and was wondering if there was a seal issue for the ice cause my ice would melt into water as you explained earlier in this post. but when it is full of ice as you showed in the last picture it only melts a little bit leaving a small amount of water trying to figure out if this cooler is as good as it should be for it being free on the side of the road. also i find that the cooler is very well made for it to hold ice as it should and what is the real use of the valve relief pressure button, like when should you use it to release pressure inside the cooler?
