#OrbOne instructions say 15g of coffee, regardless of grind.
Tried medium grind for ~4oz output, but had to remove 2g of coffee to fit heat sink (it still seated poorly). Ugh.
Tried fine grind for ~2oz output and used provided scoop, which holds 12g. Ugh.
Having to pre-heat water before attaching top (suggested in fridge magnet and videos linked from quick start guide) is weird.
Expensive yet pretty moka pot alternative, fine for short #espresso shots not so much for regular #coffee.
