Centrifugal juicers grind up produce with tiny teeth on a rapidly spinning basket. The juice is then forced through a fine mesh sieve. This method works quickly but tends to produce a lot of foam which some find unappealing or feel causes oxidization of their juice. Centrifugal juicers work best for juicing carrots, apples, and other hard fruits and vegetables versus high fiber leafy greens like wheatgrass and kale. They’re light, easy to set up and use, and easy to clean with removable dishwasher safe parts. These juicers are speedy but tend to be loud (which could be an issue if you’re juicing early in the morning while people are sleeping).  They’re affordable and great for those just getting into juicing with quality models starting at $50. 
Masticating juice extractors are also known as slow juicers because of their working mechanism that uses a slow rotating auger to crush the fruits against a stainless steel mesh at only 80-100 RPM. They do not shred or cut the fruits with blades like a centrifugal juicer, which makes them excellent for leafy greens as they get the best nutrients out of them at an extremely slow speed.
Comprehensive warranty: A good warranty can also add value to an expensive juicer. Our picks have 10- and 15-year warranties (the longest we’ve found) on both parts and motors, whereas some companies will cover only a motor. Although most of the parts on a slow juicer don’t wear that much, juicing screens can occasionally break, so warranty coverage for them is important. A long warranty on the motor isn’t a bad thing, but juicer motors seem to be pretty sturdy and not as susceptible to breakage as individual parts.
The major disadvantages of this type of machine are the noise, heat, and oxidation resulted from their great speed. This oxidation can cause a loss in nutrients in the juice, thus reducing the juice quality and fridge life. Besides, while they’re good for thick, hard, crunchy fruits and veggies, these juicers are much less efficient in handling leafy greens.

Though some buyers have complained about fussy assembly, I didn’t have any trouble taking the VSJ843 apart or putting it back together. None of the parts were fidgety or stuck to each other; everything locked into place and unlatched easily. The machine comes with a 15-year warranty on the motor and parts, which means you can juice with confidence for a very long time.


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.
Part of a Healthy Lifestyle* According to the USDA, "The benefits of eating fruits and vegetables daily are undeniable. People who eat more fruits and vegetables as part of an overall healthy diet, are likely to have a reduced risk of some chronic diseases, including heart attack and stroke, certain cancers, heart disease, obesity, and type 2 diabetes. It's also been proven to reduce the risk of developing kidney stone, decrease bone loss, ease muscle aches, alleviate high blood pressure and add years to your life." * Source: USDA, 2012 "Healthy Eating on a Budget." www.choosemyplate.gov
This means you can make like a gallon of juice in one go without growing your arm muscles. Changing of the juice collector is a breeze also, because the spout is designed so that it can be lifted up during changing to prevent dripping. No rocket science here, but this little detail in design deserves a shout out – I’m sure the idea comes from someone who does make their own orange juice.
Masticating juicers are also very popular because they are able to handle more types of foods. For instance, nuts and frozen berries can be handles by most masticating juicers. If you like to juice green leafy vegetables or wheat grass, masticating juicers are likely to be the best option for you. These juicers are also referred to as slow juicers, meaning that many people regard them as producing juice at a slower rate. In all reality, masticating juicers produce juice just about as quickly as any other juicers, but their internal parts move more slowly. Slower moving parts usually mean less chance of breaking, and wider margins of error when trying difficult foods.
Warranty: No matter what kind of juicer you're getting, you want it to last. You should always get small appliances with some level of warranty, but normally the longer the warranty, the better. Not only does it show that a company is confident in its product, but it also means that if something does break, you won't have to shell out any extra cash.
