Once I finally realized you had to press both the Lock and the On button at the same time, not separately, I found I was far more pleased with this blender
I treated myself to this thinking it would make pureeing soups easier, but it's actually not! I think a blender works much better! It takes a long time to get everything blended! The controls are a little difficult as well!
I love the blender and didn't even think about the fact that it is metal. It is a great blender (so far) but when I was washing the pan, I realized that it had scratched up the bottom of the pan. Seems like there needs to be a plastic or silicon bumper on the bottom to prevent scratches.
It works as intended but gets very hot, when it does this it produces an odor of melting plastic. Which makes me feel concerned, but it has not yet broken.
