Familiarity: I gave it as a gift but have feedback to share
Gave this to my dad as a gift and he told me that it kept his beer nice and cold. Wasn't able to confirm that it kept the beer cold and carbonated for up to the advertised 24 hours, as my dad consumed the first batch in less than 2, but that very fact makes me think that those first 2 hours kept the beer in such a deliciously cold and bubbly state that he couldn't help himself from drinking it in one sitting. And that alone is reason enough to recommend it, whether or not the beer stays in optimal condition on the 24th hour. Which I'm sure it could have.
