just got this in monday and this is what i have been waiting for this since the first nova's came out. i don't know what took them so long but thank you jesus and amen!!! this thing rocks, the 1.5dc is heaven in a vape for me... just loving it if you don't have one pick one up you won't be sorry... now if mv will keep the wholesalers away from the replacment heads it will be all good in the hood!!!!!
