Bests & Worsts Reviews from Amazon

I love this Immersion blender. It is so powerful. However, the plastic parts keep breaking on me. The inside of the head is made of cheap plastic and it cracks and breaks. Then you can't snap it closed. I have gone through 3 of these. Also on the motor part, there is a cheap plastic ring that breaks within a week of use. For such an outstanding product why use cheap plastic?
