Query: awful and black decker won't back it up

i had bought two of them because they were a deal purchase, thinking I can keep one and let my college child have one....guess what? both of them died in the first use..I opened the boxes after the first year of purchase, obviously it was a future use...I called black and decker and they refused to back up their product. I should have checked the rating before even wasting a bit of money....I told B&D that the review sucks on this product but no back up.....I have two brand new blenders that died in the middle of my first use.....I would never buy another blender from this manufacturer because they had some nerve suggesting that I should have a local repair shop check the motors and pay for replacing it....
