I bought this a replacement for another brand of grind and brew, as I was looking for a more affordable option. Not only was there sludge in every single cup (some grounds in last cup), but it broke after one week of use. The tab on the showerhead snapped off during normal use and cleaning, so the pot will not start brewing as it always thinks the grinder lid is open. This along with the fact that the grinder is designed poorly, with too much room in it to properly grind the beans, as they are not bouncing back off of anything and being repeatedly ground in what is usually a WET grinder.
