I purchased this product for Christmas for my husband because he is a cold brew addict. This is exactly what we were looking for - it is incredibly simple in it's design and use and that is my favourite thing about it. The instructions are very clear with how much coffee and water you need and how to get the best batch out of the recipe. It takes up hardly any room in the fridge. The grind on the coffee does need to be coarse so it doesn't go through the basket - it does say so in the instructions, but I did need to adjust to make it coarser than I initially thought. 
All in all, I couldn't be happier with this - and I do think the fact that it's so simple makes it really stand out from other cold brew makers.
