It functions great. You can make many cool drinks with it. The combinations are extremely useful and easy to use. I have had it for half a year. Some other reviews have said the water reservoir leaks over time. Because of this advice, I have never removed the water reservoir, and I have never seen water leaks. The drip stop does leak slighty bit after the brewing is done. Maybe its just my machine, who knows. I only put store bought filtered water, so I have not had any experience with scaling. 
Coffee is decent. I personally don’t like the metal filter. Some coffee slips through it. I use the paper filter, and it makes such a clean cup of coffee. The iced coffee is pretty good too and useful.
