I would give this more starts, but its veyr bulky.  Saying that -- items stay amazingly cold inside.  Ice didn't melt for over 24 hours.

Get lots of compliments but ice juuuust holds out til lunch. Probably about 4 to 4.5 hours. Won't make it cold for longer.

Keeps water cold for days. If I use chilled water and crushed ice I can keep the same ice for two days with numerous refills

this is a very effective container to keep things very cold or hot for a long time. If you buy 2 and you put in one the water and in the other one only ice cubes you will have cold water for 2-3 days. Just make sure you pour our the melted water into your second canteen or drink it and the rest of the ice cubes will last for days !

The ultimate in cooler convenience!  Who REALLY needs ice for 5 days?  I need ice for 48 hours, at the most, but I need to be able to transport my cooler around the camp, tailgate, beach, and on the boat without the extra hands a fully loaded, hard-sided, "expedition" cooler would require.

The IceMule family of coolers is ALL YOU NEED!

Keeps my drinks super ice cold - just what I want all day long. the ice stayed as ice cubes for maybe 4 hours I guess. Nice price too

ice lasted about a day and a half in the Caribbean.  It was never kept in direct sunlight but it was pretty hot there.

Holds ice really well. We used it for a weekend of camping in the summer heat and even with getting in and out for meals it still held ice for a couple days.

I only bought this cooler because of the claim of 4 day ice retention.  We go myrtle beach on four day trips.  Perfect cooler!  OR is it?

I loaded my cooler with 10-12 bottles of water and 2 bags of ice from the gas station.  Tossed it on the truck and off I went!  I arrived 4 hours later at my destination,and opened my cooler for a ice cold vitamin water!  Much to my surprise half my ice was gone.  We opened the cooler lid about 5 times that evening,and by morning the cooler was all water. Ice was completely melted.

I went to the igloo website and in the "faq" section it states their testing methods are inserting solid blocks of ice and inserting the cooler into a 90 degree oven,and simply timing it until the ice melts without opening the lid.

So I am not sure that their methods and a end customers actual "use" of the cooler is the same.

My test day was a 89 degree day according to the weather app I used.

In conclusion,will this cooler hold ice for 4 days as it claims?  Maybe in winter and if you don't open if very often!

Hope this helps You in your decision in buying this cooler.

Mine will be going back to tractor supply for a refund!

Does not keep ice from melting as long as they say it does. Only last maybe a day if that. Most the time just a few hours.

Ice lasts for 2-3 hours, and even after ice is gone, the contents is still cold for another hour! i
