We love cold brew coffee and have tried several DIY methods using cheesecloth, coffee filters, thermoses, etc.  What a mess!  And not quite worth it.  I was elated to find this cold brew coffee maker, and bought it as a gift for my family.  It is amazingly easy to make cold brew now - and very easy to clean.  Great coffee - no more tedious messing around in the kitchen and no more mess.  The only thing that would make this better is if it included a means to course grind the coffee beans.
