Ive had several magic bullets over the years. They are ok, but dont last long due to plastic parts (especially the one that drives the blade). But due to their cheap cost, buying a new one every 5 years seems not so bad.
Of course the vitamix is a superior performance instrument but the argument it produces a healthier product due to more efficient blending sounds like TOTAL BULLSHIT. For example:
"my coworker is very into smoothies and says that getting a good one like a vitamix or a blendtec is important because it breaks down the cell wall of the greens so that we can digest them, otherwise your body isn't able to process the cellulose"
The more detailed citations supporting this claim upthread are far from compelling. Furthermore, of course we cant process the cellulose! But that doesnt stop us from processing the phytonutrients that we extract from the cellulose due to mastication, cooking, blending, etc. Human nutrient assimilation has co-evolved over millenia with our primary method of extraction: mastication. This method is uniquely matched to our specific nutritional needs and dietary constituency.
Mechanical blending of plant cells does not increase our ability to digest plant cell walls. Why do you think a torn up batch of cellulose can be digested any different by a human than a long stretch of cellulose. We cannot do either.
"Phytonutrients, of which there are literally hundreds if not thousands found in our fruits and vegetables, reside inside the cells of their more fibrous components – skin, seeds, and pulp. "
This quote immediately discredits your source. No, there are not hundreds of phytonutrients in fruits and vegetables, there are tens of thousands in any given plant. While the relative nutritional value of any individual molecule will vary, claiming there are "hundreds, if not thousands" tells me the author is not well versed in plant biology / nutrition.
