When it comes to juice quality, the Omega produces vegetable or fruit juices that are nutrient-rich because of the way it extracts the liquid.

This juicer is best for juicing practically everything including leafy greens, wheatgrass, and fruits and vegetables including their stalks, skins, cores, stems, and peels. The Omega is regarded as one of the most efficient of all single auger-type masticating juicers.

The Omega has been exclusively designed for juicing purposes so expect excellent performance.

How long does it take for the Omega VRT350HD to produce juice? It depends on the type of food that you are juicing.

Fruits and vegetables that have high water content –grapes, tomatoes, apples, cucumbers, celery, cantaloupe, grapefruit, spinach, and broccoli, – will yield larger amounts of juice in a much shorter time than those with low water content such as potatoes, carrots, green peas, avocados, and bananas.

The 80 RPM power which the Omega produces is directly proportional to the relatively quiet manner in which it operates (you can have a conversation without having to yell).

The slow processing action of this masticating juicer makes it less noisy than most centrifugal juicers.

Most centrifugal juicers will operate with the sound of 88 decibels.The Omega operates at a relatively low 68 decibels.

This juicer is as easy to assemble, use, and clean. Its feeding funnel is large enough to accommodate nearly all types of fruits, albeit it is highly recommended that you first cut your vegetable or fruit into small chunks or pieces for it to pass more easily through the funnel.

Its Automatic Wiping System (ATS) ensures the juicer’s screen is free from excess pulp.

As you would expect from a premium juicer, the price of the omega VRT350HD isn't cheap, but the quality of the juice as well as the machine as a whole more than makes up for it.

The extra-fine mesh filter of this powerhouse juicer produces juice that is creamy, fine-textured, and free of sediments from the food item it juices.

In fact, the juice created by the Breville BJE200XL is indistinguishable from that extracted from more expensive juicer models.

You can pop carrots, cabbage, apples, broccoli, cauliflower, beets, and celery into it,skin, core, seeds, and all and still get velvety juice with all the nutrients intact.

You can turn hard and fibrous vegetables and fruits such as oranges, lemons, bok choy, and pineapple into silky-tasting juice in no time at all with this juicer.

This is especially important if your favorite juicing ingredients happen to be stringy and tough foods.

Because of the powerful 700-watt motor that can spin the juicer’s filter basket, it isn’t surprising that the Breville BJE200XL can extract eight ounces (or 250ml) of juice in just five seconds.

Its titanium cutting discs, surrounded by a filter made of Italian micro mesh, can extract juice from small apples in only three seconds.

The juicing speed of the Breville 200XL is capable of extracting 30% more juice than other juicers can.

You would expect such a powerful juicer to emit an equally noisy sound, right? You couldn’t be more wrong. For all its intense juicing performance, the Breville 200XL,surprisingly, is less loud than most centrifugal juicers in its class.

The kind of noise it makes is common with juicers that have powerful motors but you can still hold a conversation while juicing with the Breville 200XL if that’s what you want to know.

This centrifugal juicer is easy to assemble for use, disassemble for cleaning, and reassemble for storage.

A brush is included with the purchase of the Breville 200XL with which you can clean both the filter and blade.

The price of the BJE200XL is very affordable, and considering we rated it as the best centrifugal juicer to buy, we highly recommend it on price point alone. It won't disappoint.

The Tribest GSE-5000 squeezes out between 50% and 100% of minerals in your juicing ingredients to give you unparalleled nutrition. How many juicers can boast of that? 

Designed to excel at juicing leafy vegetables, wheatgrass, pine needles, nuts, and just about any soft or hard fruits and vegetables that you can think of (stringy and fibrous vegetables like corn, sweet potatoes, ginger, celery, Brussels sprouts, mango, and asparagus).

This juicer also allows you to process frozen berries and bananas and make sorbets and nut butters.

It really depends on what you are juicing. Expect a reported time frame of 30 minutes for 12 cups of leafy greens; that’s one cup per 2½ minutes of juice extraction which isn’t bad at all if you think about it (brewing coffee using a French press actually takes longer with a total brewing time of four minutes from beginning to end).

The Tribest GSE-5000 does produce noise, like all juicers do, but the relatively slower speed capacity of its motor – 110 RPM -- helps to keep the noise level down.

Even under the heaviest of usage, the Tribest GSE-5000 is not likely to wake up anybody. And although it isn’t as quiet as a refrigerator when in operation, you can still hold a conversation while the Tribest GSE-5000 is juicing.

The ease of use of this juicer has been made possible by the unique system design of its two gears: they operate like teeth. The gears are of class-A stainless system toensure they never come into contact with each other.

And to guarantee your control over the juicer, it has been equipped with a pressure adjustment system that lets you choose your fruits and vegetables without the typical hassle of internal clogging.

Yes, this juicer is expensive. Consider the amount you will spend on this juicer to be a good long-term investment for a high performance and durable kitchen appliance.

There is no doubt that the quality of the juice produced by the Z-510 is top rate because it retains the important nutrients and essential vitamins and minerals of the juice.

While there is no motor power to operate this juicer, there is also no threat of juice oxidation, keeping the nutritive values and health benefits of the juice intact.

The only downside is that you have to work the juicer to extract the juice, literally.

The Z-510 works well with wheatgrass, as mentioned, leafy greens such as kale,spinach, and celery, herbs, barley grass, and soft vegetables and fruits.

Because you control how fast or how slow you want to go in extracting the juice, you can control how much or how little pulp you want to have. Because this juicer is operated manually,you can have your juice smooth and velvety or full-bodied and creamy.

Unfortunately as the Tribest Manual juicer has no engine, the speed of the juicing is dependent on you and how quickly you can extract the juice.

If you are the sort of person to make juices in large batches then the time frame could become quite long as your arms start to tire.​

The sound emitted by the Z-510 is, for all intents and purposes, not like centrifugal or masticating juicers which are easily recognizable as motor power is whirring away.

The noise a Z-510 makes, like any other manual juicer, is the cranking kind which you get from the rotating motion of a crankshaft. 

Here’s the catch: operating the Z-510 will require arm strength. Hard, tough or fibrousvegetables and fruits will also need a lot of muscle to be able to extract the amount ofjuice that you need.

But don’t let the “manual” aspect turn you off if only for one thing:with a manual juicer like Z-510, the nutrients in your juice will not degrade, meaning all the hand cranking would have paid off tremendously in the long run.

The price of the Tribest Z-Star Z-510 is very affordable. More expensive than some very entry level motorised juicers, however you certainly won't break the bank with this juicer.
