So why is the Vitamix the only blender I will endorse?  It is the Vitamix engineering. Vitamix has an extensive history and warranty that backs their claims.  And why not?  This company has been going strong since 1921!  Mine has been running strong since 2011 and I use it daily.  There isn’t another appliance in my house that I can say that about.  It is an investment into the health of my family.
