Feeder tubes are the parts of juicers where the food is inserted. The larger your feeder tube, the more fruits, and vegetables you’ll be able to cram in at once. Some less-expensive juicers have tops that come off completely, similar to blenders. Juicers with feeder tubes also offer the advantage of being able to press the fruits and veggies into the juicer, helping to chop and grind them up.
This juicer is worth it's value. That said I note that since it is a sintrifical force juicer it seems to make much more frof then other slow grind type juicers and the remining pulp is still wet, so not all of the juice was removed ( or more could have been removed). I do like the eaz of break-Down and and reassemble and it is easy to clean. It is small enough for the counter or storage area. If you are starting out and looking to explore the world of juicing - start right here. Enjoy!!
