Title: Blendtech Fourside Jar
Review: The motor is powerful, but the blade bearing and the rubber seal could not prolong the 13am motor resulting liquid leaks at bottom of the jar. My jar leaking black metallic liquid smell inside the jar contaminated my smoothly. You can test your jar by filling the jar with clear water just enough to cover the blade, close the jar and press the smoothly button, observe bottom of jar for leak and check if the water changed color.Jar replacement cost $79.00 + shipping the new jar come with 3 years warranty. Some customer in the Web still getting leaks after replaced of a new jar with upgraded bearing. I will test for leaks before use to make sure I'm not drinking a contaminated smoothly.
