Query: disappointed, not durable

I bought this blender 3 years ago and MAYBE have used it 2 to 3 times a month since. I've mainly used it for drinks like Margaritas, which requires some ice crushing along with blending other liquids, but never used it for anything thick and chunky like blending fruit for smoothies. I've always found that the dial was difficult to move to each power level with a lot of resistance in turning it. It's always been very noisy even at the lowest power level (1), as if the motor was struggling to keep working. Today, it died a slow death, the blades barely turned and the motor overheated (smelled like burning wires). I'm disappointed to say the least, because my previous blender lasted 18 years with the same use! I would not recommend this blender since I've never been impressed with it even when it did work.
