IT'S WORTH IT! IT REALLY WORKS!
My feet haven't looked this great in YEARS!  They are soft and pink like a little kid's.  The cost of it is roughly twice what I would pay for a pedicure (which doesn't really get the job done.)  It has already paid for itself!  I blow the dust off through the back while it is still running so I can keep it clear while I am using it.  When uyou are done, you can detatch and rinse off the sttachment, pat it dry with a towel, and reuse it.
