The K-Express seems to be quieter then other models I have had in the past. I do really like the new puncher needle compared to the old ones, it seems to not get clogged like my other machine does. Super slim which is awesome when you don’t have much room on a coffee counter at home(ie: my coffee nook at home) so this is  Rey nice. The button on the side took me a minute to get used to, because my other machine had them on top, but I like them on the side now. The reservoir is a pretty good size when you look at the size of the machine. This, brings me to My only issue with the machine, and that is when you get to about a quarter of water in the reservoir it tells you to fill it, even though there is enough water for maybe two more cups. Other then that, I do really like the machine, and would totally recommend this. So, pro tip…keep it filled!
