I bought one of these because I thought it would make it easier to brew fresh ground coffee. The beans are ground in a chamber with screen walls and then the coffee is brewed by dripping water right through the grinding chamber. This works surprisingly well and is easy to clean since you can remove the grinding chamber and rinse it out in the sink.The problem I had is that the the bottom and sides of the brewing chamber are all mesh so water ran through the beans to quickly making a weak cup of coffee. Adding more coffee produced stronger coffee but it wasn't as full-flavored as a cup brewed through a paper filter in a standard coffee maker.I ended ditching this product and going back to a standard coffee maker and a stand alone grinder. If you like the complex flavors of a strong cup of coffee you'll probably end up doing the same.
