Oh my gosh! I love this thing!  There are so many great things to say about it. First off the system is so easy to work and interchange pieces.  The regular immersion blender works great, the chopping mechanism is awesome, it has a whisk attachment and you can even chop ice and make frozen drinks.  Everything works exactly as it is supposed to and it is quite powerful too.  Love, love, love this new addition to my kitchen small appliances!
