I've had a Waring juicer for years. It is loud and dangerous, and jumps around on the table. It does juice fruit such as apples, except that it is then a pain to clean. The Kuvings is quiet and there is less froth. OK, I'd say so far there is no froth. Kuvings makes a vacuum blender but I don't think they have a vacuum juicer.
This afternoon I juiced up some old hairy carrots. Slimy too, but I washed them. And ginger that was to the point of being soft. Clean up was easier because I remembered the injunction to rinse the mechanism out with water first. I like that there are no sharp parts. Carrots and ginger were not a combination from the book. Taste was medicinal healthful.
