If juicing slowly to preserve enzymes matters to you, reviewers indicate the auger-drive, masticating Omega J8005 juicer is your best choice. It's not so great with soft fruits and vegetables, but it's slow and powerful enough to work through any harder produce, and it can even make nut butter.
There's no consensus regarding whether juicing more slowly really preserves the enzymes in the juice or not. For those who believe that it does, the Omega J8005 is an obvious favorite because it will juice almost anything, and do it very slowly. Note that the Omega J8003 (*Est. $220) is the same machine, only with some cosmetic differences. For those who don't want to spend half an hour making a cup or two of juice, a versatile, powerful centrifugal juicer like the well-rated Breville Ikon BJE510XL (*Est. $200) makes more sense.
Versatile, but slow. Reviewers say the Omega J8005 delivers on its promises of handling even tough tasks, like mincing vegetables and making nut butter. One review we spotted even talks about experimenting with making protein bars. Others talk about making things like pasta, rice flour, peanut and almond butter and more. However, the J8005 sometimes struggles with softer produce. "With cucumber, pineapple and tomato … the yield is somewhat poor," says an Amazon.com reviewer.
Jim Rubel, an enthusiastic juicer who's made a hobby of creating video reviews of various juicers, uses a sound meter to measure the J8005's noise levels at about 80 or 81 decibels, so it's relatively quiet compared to other juicers. One thing the J8005 isn't, however, is fast; one owner, writing on Viewpoints.com, estimates the time for juicing one or two glasses and cleaning everything up at 25 to 30 minutes, and others agree that using the J8005 takes a bit of time and effort.
Super-fast cleaning and assembly times. We saw comments that the J8005 juicer's intake tube is on the slender side. Most seem to accept the smaller tube philosophically, but still wish they didn't have to spend time chopping produce before juicing it. On the plus side the Omega J8005 doesn't require much counter space, and a flip-up handle makes it easy to tote around.
While the task of juicing isn't quick, setup and takedown are reasonably easy. A video review at BestJuiceExtractorReviews.com shows the owner assembling it in about 20 seconds. It's attractive enough to keep on a counter between uses, says one Amazon.com reviewer, who adds that cleanup is fairly easy. Cleanup is also quick, with another Amazon.com user estimating it at "maybe two minutes tops."
Some questions arise, though most seem pleased. Most have no complaints with the Omega J8005 when it comes to durability. As an example, an Amazon.com reviewer who has used the juicer for several months reports, "It is a solid, well-built machine."
That said, we found a smattering of complaints that the juicer broke after a few months of use, and multiple complaints that the juicing screen cracked in short order when used for wheatgrass (several reviewers say the replacement screen broke, too). So while the majority of buyers are very happy with the Omega J8005's long-term performance, there are enough dissenters to raise some concerns.
Very Good More than 250 user reviewers combine to give the Omega J8005 a 4.4-star rating on Amazon.com, making it the most popular masticating juicer there. They say it performs very well for non-juicing tasks, but we found a few concerns about durability.

Good The owner of this website is frank about his lack of "expert" status, but he's a dedicated juicing enthusiast with a hobby of making video reviews of the juicers he buys. He selects the Omega J8003 as his favorite (which is identical to the Omega J8005 except for a difference in finish).
