Query: no longer happy

have been through many of these beehive blenders but this one was wrong from the start. did not blend enough/smelled and heated like it was about to catch fire. was afraid to use it any longer(used it about 6 times) but had already tossed the box to return it. gave up and went to a VERY expensive Vitamix and it was VERY much worth it! Vitamix is warrantied for 7 years, so the cost of replacing a beehive every year, which had been the case here, just about evens out. With the Vitamix I am eating much better, feel better, and have lost a few pounds already!!! Guess this is as much a Vitamix pro review as it is an Oster beehive con review.
