This is probably a dumb question. But do you have to have a heavy duty blender (like a Vita-mix) to add greens to smoothies? I have been using a small single serving type blender (like a Magic Bullet) to make my fruit smoothies. I just can't picture adding a spinach leaf in? Do you all use fresh leaves or frozen ones?
No doubt, the BlendTech and the Vita-Mix are state of the art and two of the highest rated. However, I own a Oster blender that cost about $35 and have for decades, and have found it worthy of most any task I ever ask of it. And, I have asked quite a bit of it over the years
The main benefit of the Oster blenders over most regular blenders is that it has an all metal drive system and not plastic. This means it is less likely to "skip" and also doesn't wear out from extended use. Even some consumer organizations have rated them fairly high. A recent review rated 2 of the Osters just below the Vita Mix and the BlendTech.
I don't use the blender much anymore as I found it is important to chew food as chewing is an important part of digestion and oral and dental health, and is associated with increased satiety. It is also great exercise for all your facial muscles.
While there are many other factors related to chewing and the results I am posting below, chewing ability has been found to be associated with heart health and longevity.
I just do not see this kind of information, even on a casual level, for the benefit of juicing.

Association of chewing ability with cardiovascular disease mortality in the
80-year-old Japanese population.
Eur J Cardiovasc Prev Rehabil. 2008 Feb;15(1):104-106.
Background: Few have studied the association between chewing ability and
Design and methods: In this prospective study, we analyzed 697 80-year-old
participants residing in Fukuoka Prefecture, Japan. Chewing ability was
assessed on the basis of the types of food that each participant reported
being able to chew.
Results: During follow-up, 108 participants died. Patients reporting the
lowest numbers of chewable foods were associated with higher risks of
cardiovascular mortality than those who were able to chew all the types of
food surveyed (multivariate hazard ratio: 4.60; 95% confidence interval:
Conclusions: Impaired dentition status with poor masticatory ability was an
independent risk factor for cardiovascular mortality in active elderly
Relationship between chewing ability and 4-year mortality in a cohort
of 80-year-old Japanese people.
Oral Dis. 2007 Mar;13(2):214-9.
OBJECTIVE: Poor oral health has been reported to be a risk indicator
of mortality, however, few data are available regarding the
relationship between chewing ability and mortality. We examined the
relationship between self-assessed chewing ability and mortality in
DESIGN: Prospective study.
SUBJECTS AND METHODS:
Participating in the study were 697 people (277 males, 420 females)
from 1282 individuals (80 years old) residing in Fukuoka Prefecture,
Japan. Data on oral and systemic health status through questionnaires,
accompanied by physical and laboratory blood examinations were
obtained. Chewing ability was assessed based on the number of types of
food each subject reported as able to chew by questionnaire.
A total of 108 subjects died between 1998 and 2002. Those with the
lowest number of chewable foods were associated with higher risk of
mortality than those with the ability to chew all of the 15 types of
food surveyed [hazard ratio (HR) = 2.38, 95% confidence interval (95%
CI) = 1.07-5.29], though other parameters including current smoking,
low serum albumin, and poor physical health status were more
significant. Further, reduced chewing ability of soft foods increased
the risk (HR = 2.65, 95% CI = 1.20-5.87).
CONCLUSION: Chewing ability
was associated with mortality in a population of 80-year-old community
residents, and may be a predictor for survival rate.
