As mentioned by others, the plastic base of the cutter assembly started cracking on mine. I was thinking of replacing it when the glass jar broke and figured it was time to buy a new blender. I barely used this blender and never used it to blend ice, and it sounds it was a wise decision. The food blended in there was not smooth, unlike the one from my new Cuisinart. I too though that Black & Decker was a brand representing good manufacturing and solid long-lasting products, but I guess it is no longer true.
