It's probably not a lot different than the MK3s. Just some upgraded components but it looks like they're all in the same place. The extruder looks a bit more complicated.
Mine is a 3 cup version and has "X17" on the bottom so I don't know that 10 is the size. That base is definitely larger than mine. Fill it to just below the safety valve and measure that. Mine is right around 130ml
I'm a glass-half-empty person. My views of a situation tend toward the negative so to me, the desire to be a mod stems from the enjoyment of saying "That's not allowed!"
I know there are those who want to keep a community safe and assure the policies are enforced but if it means they get to swat someone's nose and say "No, bad member", all the better.
The Opus is ok. I was really excited for it to come out since I wanted a grinder that could do pour over and espresso. I like the anti-static tech but the all-plastic build is a bit of a let down. It works well, is easy to dial in but I think my next grinder will be more metal.
The Decent is fantastic! True the settings seem overwhelming but it comes with a ton of presets that all you need to do is load the portafilter, pick a preset and hit a button. I was making great shots on day 1 without a lot of fiddling around. Once you get the hang of the settings, it's fun to experiment with other presets or even make your own.
Just a few hours after building my first 3D printer and running a test print, I stabbed my palm trying to trim some extraneous plastic from the model.
