I bought this because my old tamper, for some odd reason, and after many years of use, got sucked down into the Vitamix and had the end torn off.I didn't think this could happen, but read that a couple of others had the same experience. Anyway I was so happy to find that I could buy a new tamper at Vitamix for a reasonable fee and it is a new design that I like and that works very well. Bottom line is I have had my Vitamix for 10 years and it was the best kitchen purchase  I ever made!
