Bests & Worsts Reviews from Amazon

I was looking for a heavy duty blender, when I got over the sticker shock I did my homework. After searching many online sites and reading many reviews I decided to purchase the Blendtec rather than the Vitamix. After six months of simple use for making smoothies with frozen berries the machine broke down. It would spin out of control and then shut down in overload. Customer service took my information and assured me a rush repair and return. That was two weeks ago. First they said they never received it and had never heard of me, fortunately I had Fed Ex confirm they had signed for it. Last week they said it was going out expedited shipping, not here yet. My review is that this machine is too expensive to break down after such minor use. Understanding that there may have been a faulty part, the customer service is non existent. From "who are you", "we never got the machine", to "It's in the mail". Check out reviews for Vitamix and its customer service rating. This was too good to be true, let the buyer beware of Blendtec.
