At least 50% of American fridges do indeed have ice and filtered water dispensers built in and I think they’re great :) ice cold, delicious water any time of the day? Yes please.
They’re not even that “fancy/expensive” as it’s fairly standard
if i want cold water, i just let the tap water run for a bit and drink that. granted, its not ice cold, but do you really need it to be freezingly cold?
