Product Quality is Poor.

I bought a stick blender set, and the chopper that comes with the machine was not working, I then went back to store to swap the machine for a working one. We tested the chopper in store- it worked, i tested it again at home, it worked. The first time i used the machine it stopped working, this is weeks after i purchased the machine. I am so disgusted by the quality and would not recommend purchasing any Kambrook products in future.
