We have burned up many blenders. The cheap ones go quickly and the more expensive ones a bit more slowly. Until we decided to spend the money on a Vita Mix, none of the blenders worked well or lasted. This blender is expensive and loud but it makes us a great protein shake every morning. If you manage to somehow overload it and we have once, the thermal overload protection circuitry shuts it down before it can burn up. Amazon has the best price and great service. If you are unhappy with the product in the first 30 days send it back.
