The first time I used my new Hamilton Beach blender it blew up. The blender started releasing black smoke from it, before I could shut it off and unplug it; it made this loud noice. My children started screaming and ran into the living room. That was the end of the blender and the end of my children ever wanting to make a milk shake again. I had to take the blender outside, my house still stunk the next day of the smoke. It was a Wave Station Express Dispensing Blender (Black; model #54615)
