content: After wearing out several low cost units by makers, such as Black and Decker, etc. I opted to pay a bit more and purchase a heavy duty type. The KitchenAid unit is well suited for daily use. I really appreciate the fact that the grinder bowl separates from the power base, similar to a blender, so that you can dump the grounds without having to unplug the unit.The thick plastic cover/dome reduces the sound from the grinding somewhat which my pets appreciate.The power of the KitchenAid unit is great and I don't anticipate wearing out the motor, as I did in the B&D; unit.Overall, this unit is well worth the additional cost, plus if you have other KitchenAid devices, matching form factors is a nicety.
