Tested only for 24hrs, at this point- coffee easy to make, understanding the grinder portion- easy, taste of fresh coffee- good.. Easy to follow directions, only complaint and not even worth a deduction, just something to be aware of- the grinding chamber- LOUD... other then that, no complaints, good coffee, does what it's supposed to do. Yes, you have to clean the grinder, but seriously- ok, maybe it takes 30 seconds...and yes you have to either throw out the filter (paper) or clean out the gold filter... I prefer the simplicity in throwing out a filter. Overall- sure, there could be a few things easier (for convenience) but not a show stopper. Removable water reservoir would be nice, water level meter on the kcup side would be nice, quieter grinder... But it does what it's supposed to do, grinds and makes fresh coffee... First product of this type for me (with added grinder) and I can say at this point- yes, I enjoy it, well done, hope it serves for a long time.
