I love all the different attachments that come with this immersion blender.  They come in very handy--particularly the whisk attachment.  The one feature that I really dislike, however, is that the attachments just twist on.  They do not lock in place, and if you are blending something that is a little on the thicker side, the attachment constantly untwists itself (because it is not locked) and disconnects from the base unit, which is SO annoying!  By the time you've finished blending what you are working on, you have ended up having to re-twist on the attachment about ten times!  Other than that, it's great.  If I were to purchase an immersion blender again, I would opt for a brand that has a locking feature for the attachments.
