Works great! Does not do well with oranges, celery, and pineapples, but the performance with everything else is outstanding.

I wasn't going to add a review, but after reading some of the recent low ratings I must provide my opinion.

Clean up:
Its not "fun" but it is easy to clean off. The machine does a good job separating and expelling dry pulp making clean up less cumbersome. Harder fruits or veggies may require use of the cleaning brushes they thoughtfully provided.

Quality:
Does not take up much counter top space, hefty in weight, parts great quality, and make little noise

Juice Yield:
I'm was truly impressed when I fed in my celery and greens. The juice to pulp yield are about equal.
I provided a photo showing fresh apple juice.

Per my photo:
8 gala apples yields 32oz of juice..~4 apples per 16oz Jar
dry pulp in back
wet pulp in strainer can be used to make apple sauce or butter.

This is our second juicer and has by far impressed us over the Omega VRT350. (Still a good juicer just a level below this one)

Some great features are:

The "smokey" feed chute shows you the produce getting crushed! (cool to watch)
The smart cap allows you to mix and see the yield of juice you get from each item put in
The large feed chute reduces the amount of prep time by half
Leafy and more fibrous produce are easily juiced without blocking the exit chute (HUGE IMPROVEMENT over the Omega)
Way less pulp compared to the Omega (Perfect amount, you're not eating your juice but its not pure liquid)
You don't have to cut your produce into tiny pieces prior to juicing and you roll the leafy greens (way better!)
Clean up is easy with the brushes provided and smart cap.

The minute we turned on this juicer we knew it was going to be a good one.
We Love it :)

See John from Discount Juicers for all the reviews and comparisons of juicers available. Very helpful in deciding which is right for you! (Thanks John)

***Update***

We are still loving this machine. We did notice a manufacturing defect with our juicing screen so we contacted Kuvings Support and they sent us a new one free of charge. Someone mentioned in another review that when you buy on Amazon you may not have the warranty coverage. We had to send Kuvings a copy of our invoice and they had no issues with it.

***Update Aug 2015***

Juicer still working great, I make green juice regularly and thought I would share a tip on how to get it moving nicely through the juicer.. alternate what you put in for example:
Kale
Cucumber
Celery
Cabbage
And repeat

Another tip I've recently discovered is using cabbage. It pushes everything through (even fussy kale and celery) and cleans out the strainer very well which makes cleaning easy. The cabbage also gives the juice a much more balanced/mild taste.

***Update March 2016***

So Juicer is still working great, today the silicon plug just tore (I use it at least twice a week still), emailed Kuvings (this morning) since they do not offer that piece for sale on their site and they are sending us a whole new bowl under warranty(responded within two hours)! This company is absolutely amazing with their customer service, I don't think I could be more impressed! 100% worth the money not only for a great product but the service as well! Such a rare thing these days.

This is my third try at a juicer and so far this one is great. It handles hard and soft veges easily. There was no pulp in my juice. It didn't get jammed or clogged and easy clean up. It does have a lot of parts which would be my only con but if that's what it takes to get good juice so be it. You do have to cut up most fruit and veges but not as small as others. I have not done frozen treat yet but can't wait to try.

I ordered this juicer and it arrived last week. I've used it at least a dozen times and it is indeed a great juicer, as everyone else here has described. I will tell you how it is compared to the juicer I own and love, so that others can decide if they want to replace their current ones or not. I use the Omega VRT350, and have no issues with it, use daily and love it. I only bought the Kuvings Whole Slow Juicer because I needed a second juicer for all the traveling I do, and this one seemed exactly the same with a few "improvements" I thought I'd really like to have. The improvement I like the most is the bowl. The Kuvings bowl is flat inside without all the nooks and crannies that are in the Omega bowl, so it makes it a little easier to clean. The silicon flap under the bowl is bigger on the Kuvings, but I feel like the slightly smaller and less flat one on the Omega is easier to get in tightly (very important to avoid any leakage). Though, neither of these differences are deal- breakers. The Kuvings is much taller with the top on and I don't actually like having to use the pusher so much. On the Omega, I never have to use the pusher; an apple chunk, cucumber or carrot is all that's needed to push any greens down just with gravity... simply drop things in and the Omega pulls it all down into the auger. I'm hoping to get used to having to use the pusher on the Kuvings so much, though. It's a personal choice, of course, not really a design flaw. Also, on the feed tube subject, while it's very nice to have such a big opening (3"), you really need two hands to feed in greens, celery, and any other smaller cut items. A big funnel needs to be on top so one can just drop it in with one hand. Having to use 2 hands, I find I need a little more counter space. With the Omega, I can feed anything one-handed (may not be an issue for some people, but my set-up is juicer on the counter to the left of the sink so I can clean up easily). I do like the green basket/screen cleaner that comes with the Kuvings, it works great. The only other negative is that I actually need the thinner cleaning brush that came with my Omega to clean the pulp chute on the Kuvings bowl. The chute on the Kuvings is slightly longer than on the Omega bowl, so I need the Omega thin brush end to scoop it out easily, just like it does so well for the Omega.

Summary: If I were buying my first upright masticating juicer, I would buy the Kuvings Whole Slow Juicer, for sure. If I have the Omega VRT350 already and am looking to replace it with the Kuvings just for the improvements, I wouldn't, that would be money spent unnecessarily. However, I would do exactly what I just did and buy the Kuvings or the Omega for a second juicer. I am planning on using my Omega for my *travel juicer because it is smaller overall than the Kuvings. So my Kuvings will be the permanent fixture in my kitchen. I rated 4 stars overall rather than 5, just because of the slight awkwardness of use as compared to the Omega... not because of performance, which is excellent.

*By "travel" I mean via car. I drive state to state and stay places for weeks at a time so won't be without my juicer. I wouldn't risk either good heavy juicer on a plane, though, too much risk for damage as your bags get tossed all over the place.

UPDATE: I just wanted to add that after fiddling with it a little bit, I figured out how to get the silicon chute flap easily into it's slot. It's now just as easy for me to get it in as it is to get the smaller Omega one in it's own slot (yay me!). Anyway, I just insert the very tip of the top of the flap in first, and the rest of it follows as I push evenly and firmly with my thumb. Maybe hard to picture that... sorry... just fiddling with it for a few minutes initially will get it in there easily each time in about 3-4 seconds, though... we're all a little different. I know this isn't an issue at all for anyone who bought the Kuvings without ever having used an Omega (or any other juicer for that matter). Happy juicing!
