The Pure-Wave CM3 is a single speed, percussion only(hammer motion) massager and includes 2 attachments(point stick and 6-head stick).
Our Pure-Wave CM5 model also is a percussion only massager but has variable speed and includes 3 attachments(point stick, air-cushion stick, 6-head stick).
Finally, the Pure-Wave CM7 has both a variable speed percussion motor and the facial vibration motor built in to the end of the handle. CM7 includes the same attachments as CM5 plus 3 additional attachments(facial, scalp, and body). CM7 has a slightly longer handle since the handle includes the facial motor.
