My first magic bullet was a Christmas gift in 2007. It was fantastic! I made baby food, smoothies and sauces with it. In 2015 I was thrilled to get yet another Magic Bullet for Christmas. I donated my old Magic Bullet and began using the new one. I was a little bummed that it didnt come with two blades like my first one did but the Bullet appeared to be working well and I was happy with it. However, on my third time making a smoothie with it--the same smoothie I had made for years with my old bullet--it began smoking and just stopped working. Im not sure what happened, however, I am confident that whatever it was had everything to do with the machine because I never had any problems with my first Bullet. Sadly, I had too much confidence in this product to hang onto the paperwork that it came with so Im not sure if I can exchange it. Too bad, this product seems to have less quality than it formally did.
