Query: Poor Construction

All in all, I've loved the bullet for smoothies, whipped cream, grinding spices, cheese and coffee. I was never able to use the "pulse" method to chop anything. Everything I tried to "chop" (salsa, onions) ended up liquified.What finally killed it was the gear drive broke, and it is made of plastic. You can't get a replacement-all you can do is order another power base at 30 bucks plus shipping. So far, it's not worth it to me.
