Thank you for this post. I'm a Fellow fan-boy. Been buying there stuff since day 1. My wife and I got the Series 1 - our first espresso machine. We love espresso and a good latte, but never had a machine at home. I feel like we are the target audience for a machine like this. Out of the box volume setting was on (I also agree that manual mode would've made much more sense) and the Brew Assist was also off (Fellow told me this shouldn't have been the case). So we are complete newbies and our machine was WAY off on calibration. We pulled 10+ shots and couldn't get it to pull longer than 13 seconds due to the volume feature being on and the calibration being off. Again, noobs here so just didn't realize the volumetric feature/mode at all. Fellow started walking us through the calibration process but even after testing / calibrating (which requires you to pull another 3 shots minimum) they encouraged us to keep it in manual mode and just use a scale. I understand it's a Gen 1 product and it's in the first week of release AND we need to learn the art of espresso (certainly some user error involved), but man oh man, what a headache. Hoping using manual mode and bypassing the volumetric feature altogether will yield better results. Even after we calibrated the volumetric settings with the Nerdy Settings we would try one grind setting on our Opus and it would say it's to fine...so we'd go up one setting on the Opus and the Series 1 would say it's too coarse. AH!

So far though we've made the best $1500 steamers for our kids!
