Input:
We've had this blender/food processor for about 7yrs now. We use it very rarely because of how loud it is; my wife usually wraps 1-2 kitchen towels around it and still rushes through using it.  We haven't had any of the breakage problems others seem to have had.  The unit isn't very efficient or effective.  When using the blender, whether it's soft ingredients such as fruit or harder ingredients like ice, we have to stop it and push down and stir the ingredients then run it again for a little while before stopping it again to push and stir. We also shake it and sort of bounce it on the counter while it's running to help keep the ingredients around the blades or else they push everything away and create a little air pocket around them.  The food processor works ok, still we have to help mix the ingredients. Any way you use it though the noise is almost unbearable, our dogs and cats run away from the noise, I wish I could too.

Looking to buy something else in the near future; this time I will pay close attention to reviews, especially about the noise.
