I bought this item and, on the second use, the hand blender wouldn't work. Since the motor is in the hand piece and it has to be connected to the blender, there is a connection from one to the other. The connection doesn't hold tightly so the motor turn without making the blender turn.
I returned the item once, but I used the new item just once after the exchange. The second time I used it (more than a month later), the same problem happened, but the possibility to return it again exipred. I'm stuck with a blender that doesn't work.
so: NOT reliable.
