Query: Self-destruction was not a feature listed in the manual...

I love the idea of juicing and I wish I could recommend this juicer. However, it broke within a week. After just a few uses, it made an absolutely horrific screeching sound as the hexagonal piece in the base that holds the blade decided to shred itself into a pile of powdered plastic.No more juice for me.This product needs a re-design. The underlying engineering seems ok, but the user interface is terrible. It's difficult to assemble (think 3d jigsaw puzzle), awkward to clean (too many flimsy, finicky parts), and if you don't do everything just perfectly, it self-destructs without warning - a feature not listed in the manual.Sadly, and most worryingly, Omega customer support did not even respond to my email for a replacement part, so I returned to Amazon for a refund.To Omega -- an occasional lemon product is entirely forgivable. And perhaps that's what I got. But shoddy customer service is not. I'll take my money elsewhere.
