Replace a fairly goo HB blender with this one and it is incredible.  Can pulverize, mix, and blend everything I have put at it, including ice for smoothies and pureeing tomatoes for jam.  The all metal gear construction and operation allows for seamless operation with xtra power.  No slippage like a plastic gear system.  It is also compact enough to fit well on any counter as well as the industrial grey look that fits perfectly in my kitchen.  The heavy glass container retains cold and heat when most needed and is a perfect volume.  Just make sure you seat the container correctly as it does take a second or two to make sure it is set.
