Great idea, but returned.
No filter needed and the purity of glass is a phenomenal idea, and for the most part, it delivers. However, this brewer produces a somewhat dirty cup of coffee even in comparison to a French press. The glass is beautifully clear but fragile. The stir stick arrived broken and I was quickly sent a replacement. Not long after the handle on the dripper snapped off. I was did end up requesting a return which was a very simple process. I really wish I had a better experience because I was looking forward to this, but it is what it is.
