I have 4 ice chests. This is definitely the heaviest ice chest I own. Weighing in at around 32 lbs. empty, this is no lightweight. The ice chest looks nice. The black and orange is an attention getter. It is a far cry from the average looking white lid coolers.The manufacturer claims the cooler has the most insulation of any cooler. This along with the silicone gasket, and the ability to secure the lid by latches keeps the cold air inside the cooler. The manufacturer claims that the cooler will keep ice in it for 5 days. I decided to test this. Their suggestion is to pre-cool the cooler by putting ice in it overnight, emptying the ice, and then placing new ice into the cooler. I have never heard of "pre-cooling" an ice chest, so I just dumped 16 lbs of ice into the cooler, froze the blue ice, and placed the cooler outside.So. Cal temps right now are between 95-105 this week (Santa Clarita Valley). I placed the cooler under our patio, so it gets shade until about 1:00 PM, and then full sun until sunset. I opened the cooler only once per day to see how the ice was doing, and I did not drain any of the cold water.The ice lasted for 3 days. After 24 hours, about a third of the ice was gone. After 48 hours, maybe a third of the ice was left with about 2" of ice cold water. Then by the end of the third day there was just a couple of cubes left, but the water was still cold..For just having one 16 lbs bag of ice poured into the cooler, I was impressed at how long the ice lasted. I could have place two more bags in the cooler, which would have made the ice last longer and dropped the temperature in the cooler.It is a nice cooler, the best I own. The accessories are nice, but are not a reason to purchase the cooler. The cooler is designed to compete with other high end brands, and it works well.
