Have had blendtec for years!  First one repaired after thousands of uses then replaced after thousands more.  I use it sometimes several times a day!  Then I got another after warranty expired. Never an issue.  Gave to daughter and bought the professional one.  Love it. Never a problem.  I’ve had it for four years and use it so much!  I am buying another because I have to set up another place away from home and this is on my short list of things I cannot live without!
