Four things they do really well: 1) keep the can cold, 2) cover the can (is a a beer or a soda, no one needs to know), 3) keep the can balanced, 4) color identification.
These are great for keeping bottles or cans cold.
I have that and love it.
These are the best and especially because the still fit into a standard cup holder even with the can or bottle in them and the product stays cold for hours.
I ordered 3 of these a couple of years ago and they work VERY well to keep my drinks cold for a long time.But when I had friends over that wasn't enough and I had to break out my material and foam Koozies which, let's be honest, really start to look pretty rough after only a couple of uses.These, with their colored collars:1) Look Great2) Are easily distinguishable (we are assuming people can remember their color...)3) Keep the drinks cold for a long, long time (which is the main point)And they never fail to amuse me when the can slowly slides into the insulator.
I found them to do very little to keep drinks cool.
I know the advertised 10 hours may have been a little too much to ask for, but I don't feel like it comes anywhere close to that mark.
Keeps cold more like a couple of hours.
They may keep your drink at a cool temperature but not cold!
I don't like these insulated holders.
