Excellent Juicer Thats Worth The Cost
I was looking for a quality juicer that did a good job of extracting the most juice from organic produce. My previous juicer was left dripping pulp so it was not efficient at all. I specifically wanted the best juicer for celery juice as I drink it nearly daily. In my search I stumbled on the youtube channel Discount Juicers. The videos were so informative and perhaps that’s why I’ve had such an amazing experience with this juicer. I knew what to expect before it even arrived. After watching his videos I decided to take the plunge and purchase the greenstar pro. After using for less than a week a horrible grinding noise started up and I couldn’t make it stop so I returned it to amazon and had a replacement sent. I have loved almost everything about this machine. Cleaning can be slightly time consuming (about 10 minutes) but other than that it’s wonderful. Here’s a list of pros and cons but do some research and watch the videos from the above channel and see for yourself what’s good. Different juicers fit different needs. Notes: it is commercial grade and comes with a 15 year manufacturer warranty. That’s amazing. This machine is a masticating juicer which means it runs more slowly than a centrifugal juicer. But that’s the point. Instead of beating produce to a pulp it slowly grinds it to gently squeeze the juice. This means less oxidation and a more fresh nutrient dense juice. It takes about 2 minutes to juice 16 oz of celery juice and if that’s too long for a commercial setting they make plenty of centrifugal machines that will do it in 30 seconds or less. Pros: •Commercial grade with 15 year warranty •100% Stainless steel twin gears. They are work horses and since they are solid pieces there is significantly less risk of breakage (but if there is a broken gear they’ll send you a replacement right away.) The slightly less expensive version of this juicer has twin gears that are plastic on one end and stainless steel on the other. However, if you buy that model you can upgrade the gears down the road for between $100-$200 and they are worth the cost. •Included cleaning tools are fantastic! The scraper saves 20 minutes or more of cleaning once you figure out how to use it (seriously spent 30 minutes cleaning the screen the first few times and finally saw a video of how to line the scraper properly on the screen and it took about 60 seconds to clean after that). •Included accessories are also great and they have a few others you can buy to make things like homemade bread sticks which is a cool feature even if I haven’t used it yet. Multipurpose machines are wonderful and considering the cost of this one it makes it even more worthwhile to own because it’s not just a giant expensive juicer. •Pulp comes out very dry compared to a centrifugal juicer. It might be slightly damp but it’s leaps and bounds drier than anything my Breville ever gave me even after rejuicing the pulp 3 or 4 times. •Drier pulp means I spend less on produce as I get more juice out of less product. •Quality of juice is significantly better than with a centrifugal. For example: with celery juice the lighter green the better. Think of it like an apple that’s been cut and sitting out. It gets darker the more it oxidizes. The same is true with your juice. A centrifugal can spin at approximately 800 rpm. That means your produce is being exposed to that much more air at high speeds so the oxidation process increases significantly. The greenstar pro doesn’t go over 100 rpm. It “chews” the product and squeezes the juice slowly and gently in comparison. •Makes fantastic fruit sorbet. Any frozen fruit you have can go straight into the machine and it will come out looking like slightly harder soft server ice cream. It’s an amazing treat on a hot day. Cons: •Best used with hard produce. You can juice soft product but it has to be mixed with hard produce. •Cost •Cleaning can be cumbersome (takes about 10 minutes to wash and dry). I haven’t put anything in the dishwasher as it often leaves a residue and I don’t want to clean that so if your dishwasher does better than mine it probably won’t be an issue for many of the parts. Note: Again, I highly recommend you find and watch a video about how to use the included scraper to clean the screen. It’s really the best tool once you know how to use it.

"Michelin star" juicer / Reliable professional grade machine
In my opinion, based on performance, this juicer stands above the rest if you are looking for a fine masticating juicer to extract the most amount of nutrients from vegetables. I have owned several high end juicers prior and for the most part, they performed well. But none of them was providing this level of extraction. The result are vegetable juices that taste refined and potent. Assembling and cleaning is easy and takes approx. 5 minutes in total. And it is build to last a very longtime. This is a serious machine for connoisseurs and with a justified high price tag.

It’s ok if you can’t afford something else
Produces a fairly dry pulp and works quickly, can get foamy when doing softer fruits/veg or wheatgrass, needs to be cleaned often and the plastic chute is a huge disappointment due to tiny gaps and a small screen that lets pulp slide through. I bought the gse 15 years ago. How does a company go downhill on product design? Old one had no leaks, still plastic but felt sturdier. Pro:all stainless steel gears. Cons: almost everything else. I wish i splurged for the Angel Pro deluxe juicer, even at $1700. It is better than cheaper juicers, but if you want top of the line, keep searching. Maybe they should make a stainless steel option for the interior casings or as an aftermarket product, redesign the screens and housing. I’d give at least 4 stars.

A high-quality juicer Worth the extra money for extended juice freshness
The green star juicer makes excellent juice that stays fresh in the refrigerator for a couple of days. The machine is a little difficult to assemble at first. Once you get used to it then it’s a bit easier to assemble. It takes up quite a bit of storage space, so be prepared to devote a shelf in your kitchen cabinets to it. I haven’t tried the peanut butter attachments yet, but the ability to make fresh nut butter is a nice feature. It’s a bit more expensive than some of the other juicers out there, but it’s worth the extra money because the cold press feature allows the juice to stay fresh longer in the refrigerator.

Best quality juicer to make the best quality juice!
The BEST juicer and a joy to use! After deciding to retire my 15 year old Champion juicer, I did a ton of research to find the juicer that did the least amount of damage to the produce which would result in a healthier juice, a higher quantity and longer fridge life. This one seemed right on par with the Norwalk but much more inexpensive and easier to use. It is so gentle and quiet and produces the most wonderful juice. It is easy to assemble and disassemble. One perk I also like is that you can use the juicer throughout the day without having to wash it every time. You just remove the knob, run water through it and ta-da! Ready for your next juice of the day! You still have to clean after the last juice session. Also, it makes nice cream! We were using the Vitamix for that but this is much easier! Hands down, this juicer is worth every penny!

My $800+ mistake
Worst juicer I've ever used. The Angel juicer wasn't available so I decided to purchase this one since they'd upgraded their gears to all stainless; Initially the ends looked to be plastic. I live on a tropical island so I was excited to juice all types of fruits independently with a higher quality machine than I had in the past. You cannot do that with this juicer! The tolerance between the gears and the screen is too great so it can't produce enough pressure to extract the juice through the screen and turns the barrel into a soupy mess, especially soft fruit. Removing the end adjustment screw doesn't help and purchasing their soft fruit screw is a waste. Aditionally, juice leaked through the connection points and made a mess. Once you got to that point you had to pull it apart and try to save as much as fruit as possible. I contacted the manufacturer and asked what the distance between the gear and screen was supposed to be thinking mine may be broken. She was a broken record repeating to me that I needed to alternate between soft and hard fruit. After explaining I'm trying to make coconut milk & cream, passionfruit juice, mango puree, etc., and not mixed juices, she repeated the hard and soft alternating method but never specifically said it couldn't do what I needed. Few things ship direct to my island so we were forced to use a freight forwarder. I can't return through them so I had to pay an additional $84 to return this worthless machine. They have refunded my money, minus shipping, but claim they're still waiting for my return even with delivery proof from USPS. Very frustrating. Update: Amazon finally found the juicer in some returns warehouse and removed the threat of charging me again. The real and original Angel juicer (not super angel juicer which was only a US distributor) is now available so spend the extra money and buy that one. I can't stress this enough. If you're planning on doing any serious juicing of hard or soft fruit, grinding or puree to make nut butter, coconut cream or similar products please do not waste your time on this product. We've had the Angel Juicer now for over a year and it's worth every dollar.

Perfect or almost perfect juicer!
Very very good juicer for the price. Very good if you are rotating produce. The best for juicing celery! (Do not buy Omega for juicing celery) Taste is perfect, good for greens. Well made, sturdy, almost zero juice contact with plastic. Very high yields, dry pulp. Easy to clean. Is it worth the price? YES! Do not buy any cheaper one or not Pro version. Try Angel juicer if you are willing to spend much more.

Best Juicer of 2023
In past I have used Omega MM900HDS. It extracts juice nicely but screen rubber keep braking every 3-5 months on normal usage. Finally I got Tribest Greenstar Pro and the very 1st difference I felt was TASTE of juice. I can say it really preserves the freshness of juice and live enzymes of produce. Juice is squeezed very nicely. Very happy overall. Good prodcut Made in Korea. Keep it up.
