In mine it takes almost an hour to cool down a bottle of water. AND THAT IS TOO LONG!!!
Even so it’s one of those brand new fancy Samsungs! Well, it’s 34 Celsius outside, but anyway.
I will put a big basket of water into that fridge. That air-to-bottle transfer is inefficient. Water should work better, once it’s cooled down.
Or have some liquid nitrogen delivered? That would cool down my bottles real fast I recon.

The answer that immediately comes to mind is: One that keeps things cold:) Sorry, I know that’s no help but I couldn’t resist it.
