Okay, this is 12.99 on Amazon. So I guess if you plan to make multiple woot purchases today, this might be worth it, but otherwise Amazon is just flat out cheaper. I guess if you aren’t prime and have to get to $25, but still.
These are kind of nifty, basically spins the can in one direction (which doesn’t cause foam/carbonation problems) and cools your drink (if it is in ice.)
You can achieve the same thing by slowly twirling or spinning your drink in a cooler with ice or icewater.
ETA: It cools your drink 4-5x faster than just leaving it in ice, which is nice if you are impatient and thirsty.
