I have got a question that one of you more knowledgeable vapors may have an answer I have a Screwdriver and was wondering if anyone sells a DSE 901 blank cartomizer and if so where. If not I will just get an adaptor and turn it into a 510 Question 2 If I do that which would be the best resistancce a lr or rr cartomizer The battery is 900 mah if that helps If anyone could help me out here I would really be grateful
