I have been using an OXO cold brewer for the past year or so, and loved the end product, but I kept having leaking problems with the filter and O-Ring so I needed a brewer of higher quality. I have only made one batch so far with my new KitchenAid Cold Brew - the coffee was great! 

I really love the product design and the materials used. Compact enough so it easily fits in my fridge too.
