I bought this brew grinder to replace a huge and expensive Krups unit that finally failed.  It’s smaller and brews better coffee than the Krups.  It’s also feature packed and “smart”!  If you forget to clean the grounds basket, it will beep at you and remind you to do it and won’t let you brew more coffee. Its only issue is simple periodic maintenance.  You must clean out the grinding chute every now and then. The ground coffee can build up and clog the machine over time. A brush is included and it takes less than 5 minutes to do.  The instructions state this more than once so don’t ignore it. Easy to do and if you don’t,  the machine will even display a reminder!  It can brew up to 12 cups quickly and has a permanent reusable filter.  Just keep the chute clean and it will work perfectly!
