The Slowstar has a proprietary “Duoblade” auger, which has two cutting edges to chop and crush more with each rotation than single edges can. The motor uses a three-gear system that allows it to turn slowly but with plenty of torque; in our testing, we found that this translates to low-temperature juice with maximum yields from even low-moisture greens like kale.

Twin gear triturating machines are usually the most expensive juicers offering the best juice yield. Twin gear juicers employ two metal counter rotating gears to crush the juicing fodder. The precise tolerance of the gears allows the juice to flow through the gap between the gears while the large pulpy matter passes along the top of the gears and is discharged.
Then we repeated our tests with hard fruits and vegetables, using 8 ounces each of carrots and apples, 4 ounces of celery, and 1 ounce of ginger. In 2015, we tested our three picks against new contenders: the Kuvings Silent Juicer, Juicepresso Platinum, Tribest Solostar, and Omega NC800. We searched for new and notable models from 2017 and 2018 for this update, but didn’t find any worth testing.

Hurom introduced one new juicer in 2017, and two in 2016, but we don’t think any top our picks. The Hurom H-AA Slow Juicer is part of the company’s newer Alpha Series. The only differences we found on the H-AA from previous models like the Hurom Elite are the shape of the juice spout and a minor adjustment to the blades on the auger, both changes that won’t significantly improve juicing performance. In 2017, Hurom released the HZ, which has the same design and technology as the H-AA but in a different, stainless steel casing (that costs $100 more). In our tests, the Hurom Elite didn’t handle different types of produce well, and jammed. The Hurom HP is a compact vertical juicer with a smaller footprint than the H-AA (7½ by 7 by 15½ inches versus 8¾ by 7¾ by 16 inches) and less capacity in the juicing assembly. Hurom has a loyal fanbase, including Oprah, and we can’t deny that these machines are good juicers. But Hurom juicers fall short in their warranty coverage, parts availability, and customer service. Hurom’s warranty covers the motor for 10 years (good) and all other parts for two years (not so good).
The Omega VSJ843 features a dual-edged auger that looks almost identical to the auger on the Tribest Slowstar. The space on the underside of the auger is roomy, so wiping out packed solid vegetable matter with your finger is easy. In his video review of the Omega VSJ843, Kohler mentions that the Omega had a few stoppages as he juiced two pounds of carrots, but we didn’t experience that during our tests.

During juicing and cleanup, we also took note of how easy the machines were to use and clean. To see how efficient each model was at extraction, we measured juice yields by weight. In addition, we checked how much pulp was left over, looked for foam (which can be a sign of oxidation), and took note of if juicers backed up or jammed during juicing. We also measured the temperature of the juice, and compared it with the temperature of the produce we started out with. Finally, we tasted each juice for freshness and pulp, docking points from machines that yielded juice with unpleasant levels of fiber. Flavor is also an indicator of how much of the greens actually made it into the glass—sweeter juices had more grape and didn’t do as good of a job juicing greens.
The Tribest handled a constant stream of kale and supersoft grapes without gumming up or stalling out, unlike the Hurom Elite, which had to be thrown into reverse a couple of times. In 2015, the yield from one pound of greens and grapes was 12.15 ounces by weight, the highest yield of all the juicers we tested. When we put the Slowstar and the Omega VSJ843 (our runner-up) in a head-to-head 1-pound spinach challenge, the Slowstar produced exactly one ounce more juice than the VSJ843.
Unlike fast juicers which spins at more than 10,000 rpm to extract juice, this machine does the job with an auger turning and squeezing the fruits/veggies against the chamber wall. This minimizes exposure of the juice to the air, thus preventing oxidation of the nutrients in it. Plus, with a slow speed, you don’t have to worry about the little enzymic biological molecules being “boiled up” by the heat from the motor and destroyed.
Easy to clean: We’ve found that all juicers have one thing in common—they’re a bit of a pain to clean. The parts aren’t dishwasher safe, so you have to clean the components by hand. And they have a lot of small nooks and crannies that can trap gunk. We looked for vertical juicers that come with specialized brushes to make cleaning easier, and considered horizontal models, like those from Omega, that are a little simpler to clean because the juicing screens aren’t as big.
An efficient design allows the Slowstar to crank out a high volume of juice within a small footprint of 6½ by 8 inches. The feed-tube opening is a relatively wide 2½ by 1½ inches—wider than the 1½-inch chute on the Omega J8004—which helps reduce the amount of vegetable prep you’ll have to do beforehand. The solid waste collects cleanly in a waste container that’s included. The Slowstar has a reverse button in the back in case you need to dislodge stuck vegetable matter, but I never needed to use it.
We got more juice out of the Kuvings Centrifugal Juicer NJ-9500UB than any other machine we tested. All that remained was a small amount of pulp that felt relatively dry to the touch. The Kuvings did an excellent job extracting juice from hard and soft produce in virtually all our tests. Since getting juice is the whole point of a juicer, the Kuvings got top marks.
For your absolute peace of mind, you can go for the more expensive brands and models which guarantee lifetime warranty. If you are a newbie at juicing, however, and are not sure if you could stick with juicing for life, it may be wise to go for cheaper brands which offer limited warranties. You may also look for cheaper brands which do offer lifetime warranties for certain parts.
Do you enjoy the finer things in life? Are you looking for the ‘Rolls Royce’ of juicers? If so, look no further than the Super angel all stainless steel twin gear juicer. As its name suggests, its made from 100% stainless steel metal, which puts it into a class of its own. Stainless steel has awesome benefits apart from the fact that its super sexy looking – its also extremely durable and very easy to maintain. We also believe that juice tastes better when its come from stainless steel (as opposed to plastics). This juicer is also the number one performer when it comes to juicing leafy greens, so click here to read our review and discover more about the beez neez of juicers…
