Nama J2 vs. Vitality 5800 vs. Kuvings REVO830: Which Juicer to Choose?

Enjoy a fresh drink with a juicer

Nutritionists and experts recommend filling your diet with raw, healthy foods. Cooking food means a considerable amount of nutrition is lost, meaning that our bodies don’t get all the possible enzymes and vitamins.

Consuming natural fruit and vegetable juices is an excellent way to maintain a healthy diet by eating raw foods. The juice ingredients have been specifically chosen to provide benefits such as reduction in inflammation, ease digestive issues, improve circulation, fight toxins and boost immunity.

It’s best to drink a glass of fresh juice first thing in the morning, at least thirty minutes before your first meal. Doing this means that your body will immediately take in all the nutrients contained in the fruits or vegetables used. Make your juices for the morning with health and energy-boosting ingredients, such as oranges, bananas, berries and apples. 

Before bedtime, consider making your juice out of kale, cucumber, lemon, basil, rocket and ginger. The combination of these fresh and healthy ingredients can help with losing weight, as well as reduce fluid retention, gas formation and bloating. It’s also super delicious!

Which type of juicer is best?

#1.    Nama Vitality 5800 Cold Press Juicer

$399.00 FROM Nama Well

There are two Korean cold press juicer manufacturers who lead the world when it comes to technology and performance. Nama have partnered with one of them, Hurom, to develop the Nama Vitality 5800 Cold Press juicer. 

Using Hurom Alpha+ Juicing Technology, the design has been optimised by Nama with their Pure Press Technology™ to achieve one of the very best juicers we have ever encountered. This highly-rated juicer similarly uses slow speeds and efficient power to retain more nutrients and flavors in the juice.

That extraction efficiency gives a juice that is deep in colour, rich in flavour, and teeming with micronutrients. Because the Nama gives one of the smoothest and most pulp free juices, those nutrients are quickly and easily absorbed by the body, giving you a superdose of vitality every time you juice.

With an optimal 43rpm turning speed on the auger, juicing is still surprisingly quick and the quality and quantity of juice produced is simply outstanding. Because there is very little chance for oxygen to mix in the juice, it can be kept for a few days in the fridge without losing the abundant micronutrients.

We achieved some of the highest juice yields (the amount of juice compared to the original weight of fruit and vegetables) we've ever seen, even when juicing kale which is notoriously tricky to juice. However, it's also one of the most expensive on the market.

With other juicers, additional accessories like the large hole smoothie screen and homogenising blank are often sold as optional extras. Given that these are included and taking into account the ingredient savings over time because of the Nama’s extremely efficient extraction rate, although it’s not cheap, the Nama is very attractively priced. By saving on the waste that less efficient juicers create, we are confident that the initial outlay will be recouped many times in the lifespan of this excellent juicer. 

This machine comes with three different strainers, so you can use the juicer to make more than just juice; you can make smoothies, plant-based milk, and frozen desserts like sorbet and nice cream.

The Nama cold-press Juicer Vitality 5800 is a beginner-friendly unit that is straightforward to use.

The pulp and juice container comes with a handy lid for easy storage. Plus, with your purchase, you also receive a recipe book as an inspiration guide, as well as a quick-start guide to get you juicing that much faster.  This juicer also comes with a detachable pulp container and cleaning brush for easy cleanup. 

The feed chute is not as wide as some juicers we've tested, so we had to chop larger fruits up before juicing, but this is a minor gripe on what is one of the best juicers we've tested to date. 

If you’re looking for a juicer that’s light enough to move in and out of a cupboard regularly, it’s worth noting that at 14.1lbs/ 6.5kg this is quite a heavy appliance.

The only downside to this juicer is that there was a little bit of wobbling and squeaking while it was in use, but not enough to be bothersome.

#2.    Nama J2 Cold Press Juicer

$550.00 FROM Nama Well

A Nama J2 cold press juicer is a great choice if you are looking for an easy and quick way to make your own fruit and vegetable juice.

If you're not already familiar with the Nama J2 and are looking to learn a bit about it, we'll begin by covering the features that have allowed it to gain such notoriety in the juicer world.

Starting from the top, it's most notable for being a self-feeding juicer. As a result, ingredients placed in a chamber on the top of the unit are juiced automatically once it is turned on, without the need for any supervision.

Obviously, this saves a lot of time as you don’t need to stand next to the J2 feeding ingredients for 5 to 15 minutes. Instead it does all the work by itself, making for a very smooth process that is undoubtedly a large factor in the J2's popularity.

With its original juicer, the Vitality 5800, Nama put its best foot forward. That model performs quite well; employing Nama’s patented Pure Press Technology ™ which combines elements of torque, speed, and filtering in a manner that provides significantly more juice while retaining the high nutrient value expected from a cold press juicer.

As good of a juicer as it is, Nama wasn’t satisfied with their current level of excellence. Gathering feedback on the drawbacks and minor irritations cited by their customers, they threw themselves into the challenge of completely transforming the juicing experience. 

From this was born the Nama J2. 

Nama has taken any negative feedback they received from users of their original juicer, the Vitality 5800, and made specific design changes to the J2 in order to eliminate those issues.

The main complaints that the original Nama Vitality 5800 users reported were:

• Small Feed Chute – This requires extra chopping to make the produce small enough to fit in the chute, significantly increasing prep time.

• Pulp Outlet Chute Clogging – Even with that extra chopping, the chute (as with other vertical juicers) eventually gets clogged. Requiring users to take the juicer apart, clean, and reassemble before resuming juicing. 

• Time To Prep & Clean-Up – The two above issues combine to add significant extra time to juice. This is a common issue with many juicer models across the spectrum.

• Most of the adjustments we’ve seen in juicer designs over the years are incremental in nature but every once in a while there’s a step change that takes things to a new level. The Nama J2 Cold Press Juicer offers one such step change – the concept of hands-free batch juicing.

This means you can load a whole batch of ingredients into the large hopper on top, switch it on and walk away while the J2 automatically juices for you while you do other things. There’s minimal prep needed before you load the juicer because a rotating blade slices ingredients and feeds them into the masticating chamber where they are ground by the auger and cold pressed. This gives you a highly nutritious juice with minimal oxidation, vibrant colour and intense flavour. 

Besides producing less pulp, the Nama J2 cold press juicer has additional benefits. The Nama J2 Cold Press Juicer is one of the few models that juices leafy greens and wheatgrass with ease. It’s the ideal juicer for producing a medical-grade medium-straight celery juice. This juicer is also capable of making nut milk, seed, and oat products. In addition to its superior juice extraction abilities, the Nama J2 Juicer can be used to make these plant-based milks, sorbets, and more. This juicer is a great addition to any kitchen, as it is easy to use and comes with a variety of useful accessories.

The J2 does an excellent job of extracting juice efficiently. Compared to other vertical juicers, however, the J2 does equally, if not better, in the juice yield and dry pulp category. 

The J2 comes in at a price point that we could call a “Mid-Range” priced juicer. While it’s not the most expensive juicer, it’s also not the cheapest. At the time of writing this review, Nama provides a payment plan option through Affirm starting at $50 per month.

The J2 has a 15-year warranty for the motor and a 2-year warranty for all other parts. 

The J2 is incredibly quiet. It is by far one of the quietest juicers that I’ve ever tested. 

It comes supplied with all you need to make your own plant based milks and textured fruit smoothies too.

#3.    Kuvings REVO830 Wide Feed Slow Juicer

$699.00 FROM Kuvings

The Kuvings REVO830 Cold Press Juicer – When evolution becomes revolution. Since Kuvings first introduced the world to large feed chute slow juicers with their patented technology, their concept has been on a journey of continuous improvement with every aspect of design, from the motor up. The REVO830 delivers their best performing model yet, which was a tall order when they were already outpacing the rest of the world with this juicer format. 

In order to cope with the work required to juice larger pieces of produce, the Kuvings REVO830 has been equipped with an upgraded motor. This motor is more power efficient than the one seen in older models yet is able to output higher levels of torque to support the added strain of the auto-cutting mechanism.

The Kuvings REVO830 boasts a complete redesign of the business end of the juicer to improve the user experience when juicing while also reducing waste. There are two main advances that make this possible and they work together perfectly. First is the dual feed chute. On one side is the trade mark flip gate lid feed chute. At 88mm wide this will accept whole fruit and deliver them easily into the path of the all new juicing mechanism. On the other side is a narrower 43mm chute which is perfect for carrots, celery and other stalky or long ingredients.

For many years now the hallmark of Kuvings juicers has been their inclusion of a wide feed chute. For the REVO830 the bar has been set even higher and the primary chute has a diameter of 88 mm, surpassing the previous record of 82 mm. It also makes use of a flip-top lid, making the process safer and reducing the risk of overfeeding.

Furthermore, the primary chute is supported by a secondary feed chute designed to handle long and thin ingredients such as carrots or cucumbers. As a result, this 2nd chute has a smaller diameter of 43 mm, and it leads directly down to the augur.

Thanks to both of the chutes and their optimised design, the REVO830 is able to accept ingredients with minimal preparation and in some cases can juice them whole, saving lots of time on both the juicing process and ingredient prep.

The second new feature is the completely re-profiled juicing screw or auger. Kuvings have all but eliminated the need for chopping ingredients by adding a new auto-cutting section to the top of the auger. Working with the new dual feed chute design, this powerful cutter is the first thing ingredients encounter as they enter the juicer and it easily deals with whole carrots and celery stalks, cutting them into sections before they meet the powerful cold pressing action of the mechanism below.

At the base of the feed chutes, Kuvings has integrated a new auto-cutting feature into their classic juicing mechanism. This works via a new element at the head of the augur which rotates with the motor and cuts away chunks of ingredients as they are fed down either chute.

By automatically cutting ingredients the mechanism ensures that each chunk is sized suitably for juicing, helping the REVO830 to extract optimal yields with high levels of vitamins and minerals.

Ingredient preparation is possibly second only to ease of cleaning as a concern that people have when choosing a juicer. Being able to throw large chunks of veg and whole apples into Kuvings juicers was already a winning feature with other models but we can honestly say the REVO830 is a game changer. The auto cutting feature at the top of the new juicing mechanism almost completely eliminates the need for any ingredient preparation before you start juicing. It’s hard to believe until you see it for yourself – check out the product video above.

The ease with which it deals with whole carrots and celery stalks is a thing to behold and the REVO takes the title as our new ‘best in class’ model for juicing celery. It’s not just celery where it excels though. It offers exceptional total juice yield and we promise you, there is no other vertical slow juicer that will outperform the Kuvings REVO830. This means a better return on your investment over time, as every penny spent on ingredients goes a little bit further.

The Kuvings REVO 830 features a range of innovative features, including a “quiet” motor so users can juice day or night.

A newly-designed, easy grip Smart Cap makes it easier for the user to mix juice in the bowl, stop drips and you can even close the cap and do a pre-rinse with water, before cleaning. Even the juicer’s jugs are easy to grip and even easier to store, newly-designed, square and fitting neatly inside each other for easy storage. 

The Kuvings REVO830 sits at the very top of our range for those who want the health benefits to be found in the most nutritionally complete cold pressed juice. Your original investment in this premium juicer will also pay for itself over time with higher juice yields and therefore less waste. A superb piece of kit for the healthy kitchen.

3 Best Juicers Comparison: 

Kuvings REVO830 vs. Nama J2 vs. Nama Vitality 5800

Final thoughts：

Kuvings REVO830 vs. Nama J2 vs. Nama Vitality 5800: Which is best?

Whether you choose Kuvings or Nama, they both have excellent yield. This means that by using these juicers to reduce ingredient waste over time, the cost you spend on the juicer is worth the extra up front, and it will pay back to you in the future. While there is less margin between them, if one had to pick an absolute winner in terms of juice yield, the Kuvings REVO830 had a slight lead in terms of juicing performance.

They are all easy to clean. The hardest part of cleaning most juicers is the juice filter or strainer, which requires some scrubbing. The Kuvings juicer is a little different though, as they have designed a nice wraparound mesh brush that gets most of the fibers out of the filter while rinsing the filter under the tap, saving you some time.

Given that they are all slow juicers, the juice quality is good and they don't pour too much pulp into the finished juice. At the same time, they also deliver richer, tastier, darker juices. Cold pressing also reduces oxidation and gives the juice a longer shelf life.

All of these slow juicers come out of the box and are very easy to use. There is no noticeable difference in the number of parts to assemble or how they fit together. They all feature safety interlocks, meaning you won't be able to open them if they're not assembled properly. This prevents damage to the machines and ensures that children can use them safely.

Probably the biggest difference between these three juicers is the total time it takes to juice.

Slow Masticating Juicers process ingredients at a very similar rate to most juicers, so there's another major area when looking to save time—ingredient preparation.

Nama Vitality requires the most chopping block action before you start. You have to add the ingredients yourself.

The Nama J2 certainly offers something new that appeals to many – the concept of hands-free juicing. You fill up the large hopper on top, turn it on, and it juices without you having to feed the ingredients yourself. You can do other things like watch TV, take out the trash or chat with friends while it juices up.

We did note, however, that the actual juicing process can take a little longer on this self-feed juicer than some of the other juicers on this list, but a big part of the appeal is that you're free to use that time to get on with other things .

The J2 doesn't completely eliminate prepping ingredients before you load the hopper, but it's a lot less to do than a small chute-feed juicer.

The Kuvings REVO830 is the most time-saving tool when chopping ingredients because it almost completely eliminates the need to chop ingredients.

First off, Kuvings only makes slow juicers with large feed troughs. The flip-door lid feed chute has also been widened to 88 mm – the largest yet – so even larger apples can be juiced whole.

They also added an extra feed chute for long ingredients like carrots and celery. This means you can put whole carrots and celery stalks in your juicer.

Second, Kuvings revamped the juicing auger, adding an automatic cutting function to the top. If chopping fruit and vegetables isn't your thing, the REVO will chop it for you at 60 strokes per minute, unquestionably the best in its class, minimizing prep time.

So the big winner in this article is Kuvings REVO830 which is slightly better in terms of performance and best in terms of time saving and ease of use.
