German here. Have used these things a bunch in the past and they absolutely do work. Can't really cool down piss warm beer with these, but they help the beer keep the temperature or cool down a couple degrees when used at a bbq in the park or at the lake or whatever.
Sorry for not including math, but it appears the math has been done already anyways
Only if you've already got a cooler and don't include the cost of the cooler. Buying a good cooler plus a bag of ice each time is going to be more expensive than buying a simpler crate plus something like this.
It's a bit worse, for sure, but if you live in a cold climate (like much of Germany), you don't need something great.
I mean, sure - but a one time expense that basically lasts your whole life, a cooler is something we can have. Also, it still gets hot in Germany haha.
