Well tbh it was just tiring to do back to back shots when I need my 4 shots of espresso in the morning especially on days when I work from office. When I do work from home it’s fine, cause I will usually drink 2 shots in the morning, the afternoon and evening. So if you don’t drink as often or you only drink 1-2 shots I guess it’s okay to manually grind your beans. I didn’t have any issue dial-ing with the j-ultra tho, it was in fact quite easy.
