Except it does NOT exist.. The ECOSmartPen is the most innovative, smartest vape pen on the market today, Not to mention, I was taught LONG AGO.. ...when something is said to be the "most" "best" any of the "ST" words... It means NOTHING... ...it's PUFF.... I see that it is still holding true especially with MYDX ... but what makes it better is that the "most innovative" doesn't exist.. and IF it did... it would NOT be Yazie "invention"... he had a license for the it.... HEY wait, did he ever pay the Licensor?
