Query: black and decker food processor

Everything has to be lined up just right for the machine to turn on. Its a safety feature. I can't seem to line it up right and get frustrated. My husband doesn't have this problem. It works for him every time. He prides himself in it. I also think its lightweight and plastic. Its quality is average. If I had to purchase a food processor again, I would look for one that was strong and durable and easier to figure out that its assembly is correct before I turn it on.
