A twin-gear juicer such as one of those in the Tribest Greenstar series can extract the most juice from greens like kale, spinach, and wheatgrass, but isn’t good at juicing fruit. The juicers in this series are specialty machines usually used in professional juice bars; they’re also quite expensive. We did not test any twin-gear juicers for this review.
Unlike fast juicers which spins at more than 10,000 rpm to extract juice, this machine does the job with an auger turning and squeezing the fruits/veggies against the chamber wall. This minimizes exposure of the juice to the air, thus preventing oxidation of the nutrients in it. Plus, with a slow speed, you don’t have to worry about the little enzymic biological molecules being “boiled up” by the heat from the motor and destroyed.

"I absolutely love this juicer, it is so fast to juice and simple clean up too. I line the pulp container with a plastic produce bag and put my glass directly under the spout so I have two less parts to clean. Using this system, I only have three parts to clean, all are easy to clean and dry. I have very little time in the morning, I can barely make it to work on time, but since clean up is so quick, I have made a juice every morning since I received this juicer. I was impressed at the speed of this juicer and with very little noise. (I get a lot of juice too!) I also like that this juicer does not take up a lot of counter space, it's fairly compact compared to others I have researched. AND the price is extremely reasonable! A friend of mine came over while I was juicing and she was so impressed with this model that she asked me for the ordering information! In the past, she has had 3 different juicers and she said none of them compared to this one! Honestly, I can't think of anything about this juicer that I would change...maybe it would be helpful if they included a juicing recipe book! Thank you Amazon for the quality product and the fast shipping!"

Also, we realize that $300-plus is a lot to spend on a small appliance, but we’ve found that paying a bit more for your machine up front is worth doing. Juicing is a costly habit no matter how you do it. Although the initial investment on our pick is high, you won’t be throwing money out with partially extracted, soggy pulp. You can also check eBay and Craigslist for used juicers, especially Omegas and Huroms, because they’ve been around a while. A lot of people sell their machines after realizing they’re not ready to give up the money, counter space, or time required to make juice regularly. You won’t be able to take advantage of the warranty, but you can get really good deals (and even resell yours if you get tired of it).

For those just trying out the juicing trend, on a budget, or who will only be juicing every now and then; the Hamilton Beach Big Mouth Pro is an incredible value. Retailing at only $50 it has features that rival much more expensive models. A 3” chute means much less time prepping fruits and vegetables for juicing–it even handled whole carrots and whole apples with no problem. Easy to assemble, clean, and use; this centrifugal model has a 1.1 horsepower motor (equivalent to about 820 watts). It’s small enough to fit under the counter but note that it’s largely made of plastic so it may not have the aesthetic you’re looking for. It comes with a small 20 oz pitcher but the height of the juice spout means it’s simple to use your own pitchers for larger batch juicing (and it has a large external pulp container too). This model did a fantastic job on all our tests and produced high quality, high volume juices–it even handled notoriously tricky to juice kale extremely well. We highly recommend this juicer as a starter model or for those who may not juice often but want the option to. It comes with a 3-year warranty and receives gret reviews online.
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.

Thanks to its game-changing self-feeding hopper, this pretty Hurom H-AI Slow Juicer chops and pushes down fruits and vegetables for you. In addition to being less work than other juicers on the market, the Hurom's automatic operation makes it harder to clog or overfeed the hopper. But because it's pricey, this luxe model's an investment we would recommend for true juice enthusiasts. Available in rose gold, slate blue, or silver.
Juicing is a unique way to naturally process your fruits and vegetables to maximize the nutrition you get from your foods. By chopping, crushing, and squeezing fruits and vegetables, you are helping to release all the micronutrients found within the cell walls [1] These micronutrients are very beneficial to your health and can benefit nearly every aspect of your health. Simply put, Juicing is good for you! One of the most effective means to ensure you are getting the most of these powerful enzymes and micronutrients is to juice with a high-quality juicer made just for juicing! Research has shown that using juicers, rather than blenders, is a much more effective way to release natural anti-oxidants found in fruits [2].
