There aren't many options that offer both carafe and single serve options in a home machine. But of the few that I found and/or tried, this is the better option, hands down. With only a tweak or two, it would absolutely be in a class of its own, if it's not already.
The goods things...
Water volume - I mostly use it as a single serve machine and I get about 6 large 14oz cups from a tank, which covers at least 2 typical days or more for me, and runs out just before the bean hopper does - nice.
Consistency - Each cup has been just like the previous with the same settings, i.e. same volume, same grinds in the basket, same flavor, etc. (Another machine from a different mfgr often times wasn't even close between cups).
It's quiet - The grinder is the quietest of any that I've compared - really impressive.
From my phone, from my bed - With just a few taps of my phone, I can start the machine from anywhere.
Added controls - At least from the app, there are nice options to adjust various aspects of the brew, such as grinding time, bloom, etc.
Cleanup - So far has been quite simple. The grinder doesn't make a horrible mess all over as I've seen in others, and I like that! Takes me less than 30 seconds to clean the basket and mesh filter between cups. Well worth it knowing that I'm getting a fresh bean-to-cup every time.
Size and style - Fits beautifully underneath my cabinet and takes up much less space than a typical machine, especially when you have a separate grinder! And it looks so much better, too!
What keeps it from getting the 5th star?....
The slider - Don't forget to confirm the adjustment. The slider is what depresses the stopper in the basket so that it will release and fill a single cup since a carafe is not underneath to press it manually. I've forgotten it a time or two, and fortunately, it didn't overflow. Instead, it was like an infusion where the grounds sit in the water for an extended period of time. The cup of coffee was good, but it caused a little silt in the bottom of the cup which leaves an off-putting texture in your mouth. I think that's something that could be fixed on future models.
Different settings based upon access - Not all features and/or adjustments can be made manually. There are more options for control via the app than from the manual touch pad interface. No bloom selections, grind time adjustment, etc. from the manual controls. That's unfortunate.
Restricted height - Would be really nice if a small portion of the drip tray could be removed to accommodate a larger travel mug. Seems that everyone likes about 7" clearance, but I have a couple of travel mugs/thermoses that are just a little taller. The additional inch or two that that would accommodate would go a long way.
And, too much height, sometimes - Although any splatter that I've gotten has been rather minimal, a foldable stand that would accommodate a shorter mug would be nice. As I mentioned earlier, I use a rather large mug and there will occasionally be a few splatter droplets outside the mug. But a smaller mug results in a larger mess that could easily be avoided if the mug were lifted an inch or two.
So all in all, no regrets. I know that the imperfections are probably kinda picky, but at a price point that this machine falls in to, I don't feel like it's asking too much. And at the end of the day, it's a MUCH better machine than any others of a similar price.
