I wish they had this kind of coin operated machines so you could use them in public.

至 TessX : There are pulsators with adjustable speed and this pulsator is actually set at a rather high speed
that is more suitable for milking sheep at 100-120/minute than cows that are milked at 50-60/minute.
The vacuum level is normally around 40-45 kPa for portable milking machines and should NEVER be
stronger than necessary as milking should be a really comfortable experience to enjoy!
