In case of fruits with fibres (like ananas...etc) there is a tendency that during the extraction the fibres are sticking into the small hole which results into an un-efficient way to get t the juice out of the fruit. Furthermore the engine starts to heat up, and I presume this isn’t so good for the long live of the entire machine. By reading my comments, I’m in the hope to get some feedback and perhaps some gifts to push your design to be even more powerful and to an exceptional satisfying level of performance for most if not all of your. Having Said that, overall I like this machine.
