To quote one of the people who made also the acquisition of this model, I was looking for a device with the screw system as cheaply as possible, and keeping the nutritional value of aliments.Et there, frankly I am VERY SATISFIED, the product itself (Robust, easy to disassemble, reassemble, clean) ... Also I was looking for additional information on the SITE "Green Living" where there are video testimonials and some very interesting info the juice, the benefits .... and use of this type of device.
