All Stainless Steel Twin Gears: The Greenstar comes with all stainless steel Twin Gears for added durability, without sacrificing the quality of your juice. The advanced impeller press system rotates at a low RPM and generates minimal heat while juicing. Tamper Holder: Place the tamper into the tamper holder for added convenience. Higher Yields: Advanced heavy-duty Jumbo Twin Gears use the same magnetic and bioceramic technology as the original twin gears and extend the juicing process from two to three stages – crushing, mixing, and pressing. Reduces Oxidation: Unlike other juicers with high-speed chopping blades that create heat and impact shock, the Greenstar slowly and gently presses your juice out. This allows you to store your juice in the refrigerator for 72 hours without the loss of nutritional value. New Locking Mechanism: The new stationary latching system offers optimum convenience and an easier way to assemble and disassemble the machine
