Query: Great blender except base

I ordered this blender because of Consumer Report reviews. The blender seems to have one major flaw - a base with plastic teeth. Although the technical data indicates a sturdy stainless-steel blade, the actual mechanism that controls the blade is made out of plastic and is easily broken. I only used my blender for 2 weeks before it broke, and I am waiting on a replacement at 20% of the original cost (excluding shipping)that I won't receive for 3-4 weeks. I'll be replacing this blender very soon.
