Blizzard Beer Chiller (set of 4), fits inside foam can coolers

I saw this ingenious invention a long time ago & always wanted it. It really does keep canned beverages colder. It must be used in conjunction with a koozie, so I got a stainless-steel drink holder & together they work great.

These are an awesome idea, but they only work if you put them in the bottom of a coozie and then the beer on top. I wish they fit a standard can better so that you could use it without the coozie and have it just sit on top

I REALLY wanted to love these. I thought they would be a nice solution for beverages consumed outdoors that need to stay a little colder than they will on their own in the hot South! I just can't justify spending a huge sum on the effective solid koozies available that keep beverages cold due to the fact that I can't easily carry those around for use in a variety of settings. We tried these recently while attending a baseball game and although the fit is absolutely perfect for both cans and aluminum bottles, they just didn't work to keep the drink colder for very long and the "spares" we bought to use on drink 2 were warm before we got a chance to use them.Amazing concept, and probably works well for your home pool use or if you can keep them on ice in a cooler to swap out regularly, but just not ideal for what I was personally hoping to use them for.

These things are really small. They fit nicely, but there’s just not enough size and contact to have any effect on the can’s temperature.
