Very nice grinder. I had some quality control issues with several of the burr carrier screws, pretty disappointing for close to a $1k grinder. However, Vagif the technician at Kitchen Barista was very kind and helpful in addressing the issue and getting warranty parts to me. Well done ✅ I'm using a 54mm bottomless portafilter setup and it's working very well. Grounds are so uniform and fluffy, totally upped the flavor game from the conical I had previously. Having jumped this far up in grinder, at this point part of me wishes I had investigated an Atom series grinder more seriously but I know this one will serve me well for years and it really is beautiful. If this is your price point area I'm sure you'll be as happy as I am with it!
