I have an RTIC . Keep in mind if you put the dry ice on top it may freeze your food below... You can add some rock salt as well for long cooling.
The biggest problem with it here coolers is that they are heavy...
The RTIC products would not be available in the time frame I needed it. The coolers are heavy, but that has to do with the thickness of the cooler. If it does what they say, I will be happy.
I bought the Palm cooler instead of a Yeti, even though I could have gotten a Yeti at a discount. I really liked the price of the Palm.
