Bsr! Newbie in the tubes, which is outside the machine manual obvious, so I invested this my electric china! Premium received, so very quickly, this machine makes me lose more time than manual bending machine! jam, incorrectly filled tubes even max. Hazardous, since the tip of the cigarette falls to anyone any time, let's drive ... I even request a refund if Amazon reads this comment ... To banish! Yet a faithful customer !!!!!!
