Amberale Not as pretty perhaps but about $30aud on Ali
Not sure how this works. Would you have a link to the manufacturers demonstration video? And a link to Ali.
Do you find it beneficial, relative to a blind portafilter backflush?
@MediumRoastSteam I would think that the backflush on the Lelit E is good enough? Do you see any benefit to this for a Lelit E?
