I received these frozen block makers just in time for a camping trip. We made a bunch of these frozen ice blocks for our ice chests so they would survive the 10-hour drive.  Because of the slim profile shape, they don't take up as much room as an ice block would.  As far as storing soups, etc., they can't beat.  My fridge/freezer is low-profile, which is not very deep.  These have been a game-changer.
