These are made to grip cans so they don’t fall out you have to intentionally remove them

I was sitting in the hot tub in full sun and set my beer behind me and forgot about it for maybe 10 minutes

When i grabbed it the cooler itself was so hot i had to let go of it

After splashing some water on it to cool it off i took a drink figuring the beer would be hot

The design of the product is good i especially like that it doesnt add a lot of bulk to the can and it leaves the top halfinch of the can the part where the can narrows fully exposed so that when you drink from the can your lips touch the can only and do not touch any part of the can insulator

I did a fairly scientific experiment to test how effective this product is i filled two empty soda cans with water and chilled both in the refrigerator overnight

The results are in the image attached the simple modern insulator keeps the water significantly colder after a full hour the temperature rise is about half as much for the insulated can than the exposed can
