I was wondering I am going to be having like an extra 30 bucks to spend towards my ecigs. I was wondering what I should buy baterries or juice? I use the m401 and have about 9 or so batteries and about 300mls of juice and about 11 atomisers. I would just like some advice as to what I should put my money towards ejuice or 2 more m401 bateries. Also how long can I expect my stock that I have now to last me? I have been on the same attys for 3 months now and the batteries I have from my first starter kit still work. Thanks
