I still have one, got caught up in their free trial offer, blah, blah, blah! What have I got to lose, no good send it back. I didn't read the small print..., Still have it don't use it. Someone may need it someday. It was ok, better draw than the(and I am guessing here) C 15/C16 I started with. It was serviceable, readily available , locally as well.Both my coworkers who raved about them have returned to analog, at lease partially. Their juice was ok as well.
