I am so embarrassed to admit I had no idea this type of “mechanism” was available to have right in the comfort of my own kitchen. I literally feel top notch having guests over as I am able to whip them up a pretty fancy drink ( no charge). I did doubt myself getting it set up and ready to go, however once I made a few different drinks and experimented, I was certainly the coolest barista around. My family loves it and it certainly has saved us on our daily morning trips for coffee. Great flavor and it’s hard to “mess it up” once you know how to use it! Love it.
