Greenstar 5 Detailed Review
The Iconic Greenstar series enters its 5th Gen
The Greenstar 5 is the latest version of Tribest’s iconic twin gear juicer series. It uses the same tried-and-tested twin gear system that Tribest has refined over decades—delivering the high juice yield and rich nutrition the Greenstar line is known for.
This updated model builds on the Greenstar Pro with a sleeker design, better weight distribution, and a more ergonomic handle. It’s also easier to clean and feels more durable overall. For anyone who prioritizes juice quality and yield, the Greenstar 5 is a smart pick.
If I were shopping for a Greenstar today, I’d choose this one over the Pro or the Elite.
Greenstar 5 v Greenstar Pro
Here’s how the Greenstar 5 improves on the Pro:
- Redesigned Exterior: Sleeker look with better weight distribution and stability.
- Balanced Handle: Easier to lift—can be picked up with one finger.
- Upgraded Feed Chute: Now circular, making it easier to load produce.
- Gasket Improvements: Better sealing prevents juice and pulp leaks onto the motor body—solving a common issue in older models and making cleanup easier.
- Stronger Parts: Feels more durable with upgraded components.
- Built-in Drip Tray: Catch drips below the juice spout
- Motor: Same power as the Pro, but the Pro includes a cooling fan—this one doesn’t.
Performance-wise, juice quality, and yield are identical between the two because they use the same exact gears and same motor.
But the Greenstar 5 is easier to use and clean. The improved gaskets prevent pulp and juice from reaching the motor body—solving the biggest complaint with older models. If you love the Elite or Pro, this upgrade is a no-brainer. Unless you need a commercial-certified juicer, the Greenstar 5 is the smarter pick.
Design
Sleeker, More Stable Design
The Greenstar 5 looks great—definitely the best design in the series. It has a squared shape and better weight distribution, so it’s much more stable. Older models used to tip forward if you pushed hard, but this one stays put.
Centered, Balanced Handle
The handle is now centered and well-balanced. You can lift the whole machine with just one finger, which makes it easier to move around.
Improved Feed Chute
The feed chute is slightly wider and now circular, which makes feeding produce easier compared to the older square chute. All the plastic parts are BPA-free and feel more durable than before.
Built-in Drip Tray (With a Quirk)
There’s a built-in drip tray under the juice spout to catch drips—but it almost forces you to use Tribest’s own juice cup, since other containers won’t fit in the cutout. That’s one thing I don’t like.
Also, they don’t include a pulp collection cup. You’ll need to use your own bowl.
Reverse Function
If produce ever jams, you can use the reverse switch to unclog it—handy during tougher juicing sessions.
Stainless Steel Gears with Magnetic Tech
Inside, you get two 100% stainless steel gears with built-in magnetic and bioceramic tech. This is probably my favorite part. Unlike most slow juicers that grind produce on plastic, the Greenstar 5 uses stainless-on-stainless grinding. It’s more durable, more hygienic, and likely to last a lifetime.
Plus, according to Tribest’s own tests, the magnetic tech inside the gears can increase minerals like calcium, iron, and zinc by 50 to 200% compared to juice from other brands.
Runtime
The Greenstar has a 40-minute continuous runtime—more than enough for most home juicing sessions. If you’re batch juicing, just let it cool down for 10 minutes before starting again.
Juice Quality
If your priority is maximum nutrition—twin gear juicers are the ones to get. They’re known for producing the highest-quality juice because they grind ingredients thoroughly, breaking open cell walls to release more nutrients.
Personally, it’s really important to me that my juicer preserves as much nutrition as possible. I’m not a fan of those high-speed machines you find in department stores—they might be cheap, but they destroy nutrients and cause faster oxidation. The Greenstar runs at just 110 RPM, which significantly reduces oxidation and helps retain more vitamins and minerals. Juice made in the Greenstar can also be stored for a longer time. That low speed, combined with its twin gear system, consistently produces richer, more nutrient-dense juice.
Juice Taste
You can taste the richness in Greenstar’s juice. It’s stronger, more full-bodied, and noticeably deeper in color than what you get from single-auger slow or fast juicers. The juice has more pigment and very little pulp—delivering a smooth juice that feels nutrient-dense.
Yield
Yield is the hallmark of twin gear juicers. They generally produce the highest quantity of juice across all juicer types, especially with hard vegetables like carrots, broccoli, cauliflower, and leafy greens.
In our tests, the twin gear Greenstar and Angel juicers consistently outperformed all others for greens and vegetables. The only single-auger juicer to beat the Greenstar was the Sana 727, which achieved about 950 ml of juice compared to the Greenstar’s 900 ml—5% more yield, but it was limited to green produce. When it comes to roots, the Greenstar pulled ahead.
One thing to note: the collection cup fills up quickly, especially during batch juicing. You’ll need to keep an eye on it for longer juicing sessions.
What it can juice?
The Greenstar shines with hard veggies, roots, and leafy greens. It handles everything from broccoli, cauliflower, carrots, and kale to wheatgrass with ease. Where other juicers might clog or struggle with ginger or tough greens like kale, the Greenstar’s twin gears tear through all the fibers without hesitation.
That said, don’t choose this machine if your goal is to juice mostly fruits—say, 75% or more. A 50/50 mix of fruits and vegetables is fine because the fiber from the veggies helps move soft fruit pulp through the system. But for fruit-heavy juicing, horizontal machines like the Greenstar aren’t ideal. You’ll get better results with a vertical juicer.
Pro tip: Rotate your ingredients—apple, leafy green, then root. Always finish with a firm item like carrot or at least one fibrous ingredient like celery to help push out soft pulp and keep the juicer running smoothly.
Prepping Produce
Like most horizontal slow juicers, the Greenstar has a small feed chute. However, leafy greens are easy to juice—just roll them into a bundle and drop them in. The twin gears will suck them in automatically, which is a big advantage over single-auger juicers that need constant pushing.
Apples need to be cut into smaller wedges before juicing, but they’re easy to push through. Carrots, on the other hand, take some strength. That’s because you’re pushing them in between two gears. This extra force is a common complaint, but it’s a trade-off for the high juice quality and higher yield the Greenstar offers.
Assembly
The Greenstar has more parts than most juicers, so assembly and disassembly take more effort. It’s not difficult once you get the hang of it—but it’s definitely more involved.
To assemble, you start with the main housing, line up the dots on the twin gears, insert the juicing screen, snap on the housing cover, add the outlet knob, and finish with the top cap.
Cleaning
The Greenstar is definitely easier to clean than earlier models, thanks to the gasket that keeps juice and pulp off the motor body. But let’s be honest—it’s still a bit of a hassle.
It comes with one of the best cleaning tools we’ve seen—a dual brush and scraper combo. The stiff-bristled brush scrubs the screen and gets into tight spots, while the scraper cleans the outside of the screen effectively.
Still, it’s more time-consuming than single-gear slow juicers. It usually takes me around 5 minutes to thoroughly clean, including scrubbing the screen and all the nooks.
Noise
The Greenstar runs at 66 decibels, which is quiet compared to high-speed juicers. For context, that’s about the same noise level as a normal conversation or a running dishwasher—noticeable, but not disruptive.
Build Quality and Warranty
The Greenstar juicers are heavy-duty machines. In our experience, we’ve never seen the motor fail—even with regular, daily use.
They’re manufactured in South Korea, where some of the world’s best juicers are made, and come with a 15-year full warranty covering both the motor and all parts. That’s the longest warranty in the juicing industry, an upgrade from the 12 years offered in earlier models.
What Else Can It Make?
The Greenstar 5 isn’t just for juicing—it also works as a basic food processor using the two included blank (homogenizing) screens:
- Open Blank Screen (rectangular hole facing downward): Ideal for pâtés, mock meats, baby food, sauces, and grinding soaked nuts or beans. The food is ground between the twin gears and drops out from the juice outlet underneath.
- Closed Blank Screen (Breadstick Screen): Perfect for frozen fruit sorbets, mochi, nut butters, and raw breadsticks. It pushes the mixture through the machine, grinding it between the gears, then extruding it in a smooth, cylindrical shape through the front pulp outlet.
Accessories Included
- Dust Cover: Sits on top to keep dust out—a small but smart addition.
- Drip Tray: Catches stray drips under the juice cup. Easy to remove and clean.
- Stainless Steel Sieve: Sits on top of your collection cup to filter out extra pulp for a smoother juice.
- Plastic Pusher: Helps feed produce into the machine. There’s also a built-in holder on the back to keep it neatly stored.
- Wooden Tamper: A natural alternative to the plastic pusher—solid and feels premium.
- Coarse Hole Screen: Great if you like a pulpier juice or are juicing soft fruits.
- 2 Blank (Homogenizing) Screens: Turn your juicer into a basic food processor—perfect for nut butters, sorbets, pâtés, and more.
- Outlet Knob: Use this with the closed blank screen to shape processed food into smooth, cylindrical logs.
- Cleaning Brush & Scraper: The dual brush has stiff bristles that scrub deep inside the screen, while the scraper clears pulp stuck on the outer mesh. Genuinely one of the best cleaning tools we’ve seen.

Other recommended juicers
Greenstar 5 vs Sana 727
The Sana 727 Supreme is the top single-gear horizontal juicer we recommend—and a great alternative to the Greenstar 5 if your focus is mostly on leafy greens. It’s easier to assemble, simpler to clean, and comes with variable speed control. In our green juice yield test, it scored 5% higher yield at the slowest speed compared to the GS5. It also shares the same 15-year warranty.
That said, the Greenstar 5 still outperforms it on root veggies like carrots and beets, thanks to its powerful twin gear system. The juice from the GS5 tends to be richer, deeper in flavor, and its stainless steel gears extract more nutrients.
- Choose the Sana 727 if you want an easier juicing experience
- Choose the Greenstar 5 if you’re chasing maximum nutrition and overall higher yield.
Both are excellent machines—you just need to pick the one that fits your routine best.
Greenstar 5 vs Angel
Both Greenstar 5 and the Angel Juicer are our favorite twin gear options.
While the Angel Juicer is relatively easier to assemble and clean, made entirely from stainless steel, and delivers a higher yield than the Greenstar 5, the Greenstar 5 offers the best value alternative in the twin gear category. It provides a better price-to-performance ratio, making it a more accessible option without compromising on juice quality and durability.
Greenstar 5 vs Hurom H400 Vertical Slow Juicer
The Hurom H400 is the most convenient juicer we’ve tested. Its self-feeding hopper and screenless design let you load produce, close the lid, and walk away. Cleanup takes about a minute—no scrubbing.
The Greenstar 5 delivers higher yield and nutrition, especially for leafy greens and root vegetables, but it’s harder to clean, assemble, and feed. If you juice mostly greens, choose Greenstar—it’s a specialist. But if you juice mostly fruits or want a juicer that handles all produce fairly well with minimal effort, the H400 is the better choice.
Choose Greenstar for nutrition. Choose H400 for convenience and everyday use.
Final words
We love the Greenstar 5—it’s the most advanced Greenstar yet. Compared to older GS models, it’s easier to clean, looks sleeker, and the all-stainless steel gears add a hygienic touch. Juice quality, yield, and long-term durability are all top-notch.
That said, it still takes some effort to clean and assemble. This isn’t for casual juicers. But if you’re serious about juicing for health—especially leafy greens and root vegetables—the Greenstar 5 delivers performance few juicers can match.
If you value nutrition and juice quality above convenience, this is the machine to invest in. And with a 15-year warranty, it just might be the last juicer you ever buy.
