Glad I purchased the Nama J2
I juice carrots more than any other produce. I had a lower cost juicer that worked fine, but I felt I should only juice about 64 oz at a time because it got quite hot. For carrot juice (some celery, lemon, kiwi, apples, beets, turmeric added), these are the differences I have noticed between the $120 juicer and the J2:
1) The J2 juices much faster, so no problem with overheating, and can juice a gallon at a time, which lasts more days.
2) With carrots, I get 10-15% more juice from the J2. Still much pulp, but not as much.
As for cleaning, I find it similar in time with both juicers I have purchased. Some say they have it cleaned in 3 minutes. I could do that, but to try to get as much cleaned to minimize orange coloring, it is 8-10 minutes for me. But both are easy to clean. I like how the J2 has the pulp area with being able to open in up, so it is easier to clean for getting all out and less discoloration.
If you are looking for a juicer that you will be using often with carrots, it will eventually pay for itself perhaps. If all goes well, I will be juicing half as much in another couple months. But just for ease and getting more juice, I think the J2 is a good purchase, and I am glad I purchased it.
