I was using the Hario V60 Drip Scale previously, and it is not designed for weighing espresso shots (duh). It is laggy and bulky underneath the group head. The precision is also lesser by 0.3g after using the Acaia Calibration Weight 100g to measure it.
Again, I decided to endgame it and went straight to the Acaia Lunar. The official retail price of the Acaia Lunar is US$250 (S$339), but on their website, it doesn’t ship directly to Singapore.
