Is there a difference between the Sebenza Classic and the Sebenza 21? Or am I just getting confused by sebenza terminology? If there is I would appreciate comparison pics but explenations will do just as well. Or if anyone just has a pic of the most recent/current model I would appreciate that as well. I am considering purchasing one but have noticed some subtle differences while scrollint through the pictures on this forum. I just want to be sure what to expect before I go ordering one since I will most likely be doing it online. Thanks!
