JAWZ Countertop Blender 64oz

We have ordered this several times, including to gift to others. I am stunned at the terrible design. The last two failed within 3 uses, because of incredibly poor design. The metal gear in the base and the metal gear in the jar must be made of metal that is too soft. If you have even the tiniest of misalignment, they wear each other down to a point where the blades no longer spin. And we are not talking about months or years of use. This happened within THREE USES! Totally unacceptable. The machine seems plenty powerful (although loud), and otherwise capable, but this has completely ruined me on the model and design. Highly not recommended unless you want to have it fail shortly after getting it.
