I bought my 2 blenders around 8 years ago and am barely having to replace one of my jars.  I have never owned a product that lasts past its warranty. I use my blenders extensively (2-4 times, daily). I blend my grains into flour; make soups, ice cream, nut milk, salsa. This is a wonderfully made product. I have never been disappointed with my Blentec blender or jar. We love our Blendtec!
