Yes, even after owning a Classic Vitamix for 23+ years, my husband temporarily lost his mind and stuck the tamper in my brand new E320 machine without the lid on.  And of course the very powerful new Vitamix chewed up and spit out the tamper (duh), which I'm sure what is supposed to happen so you don't ruin your blades.  So here I am purchasing a replacement tamper, which I'm happy to see that does not cost too, too much.
