All of the internal pieces that do the work are metal (with some metal-based mesh). The only plastic piece is "smoothie" attachment, which I've, honestly, never used - as I'm a much bigger fan of just plain and simple fresh-pressed juice. But I love this machine. It's durable. Clean up is quick and easy. And the juice that gets extracted is so tasty! I highly recommend this product.
Good question! I've never used the juicer you mentioned. The motor just might be equally as strong. The problem, however, is the clean up. Check out reviews on cleaning it up. Some juicers are disastrous on clean up :(
Since it is a rotary machine, it juices with speed. I use all of those ingredients, but it does take a lot of kale or other leafy greens to make enough. I cram everything that fits through my juicer and it grinds through it with speed and ease. Clean up is a breeze. From my research, the masticating ones are more efficient, but slower and more parts to clean. Neither were acceptable to me, so chose this one and am very happy.
It takes a lot of greens to get a little juice. I've heard masticating ones are better, but I preferred the speed and ease of cleaning. There is lots of fibrous "waste," but I love the juice. This is a great product. Easy to clean. Fast.
