Bests & Worsts Reviews from Amazon

I bought this blender about tow month ago, the usage frequency is about one or twice a week. Today when i after blending a milkshake, a little black plastic chip leaking from bottom if the machine. I wondered what it was, and when i gentlly shaked the machine, i could hear the sound of some other dropped items inside the machine. So i opened the bottom cap with a screwdriver, excactly there were two more scrapes dropped from the bottom fan blakes. The quality is so worried even two months passed. I do request a replacement at least.
