so my niece that referred me to this site is sending me a care package! she said it would arrive thursday or friday. she is sending me all of her equipment! she no longer vapes, so i inherit her stuff. hubby and i are currently doing the green smart living cartomizers (808). we were going to just stick with this due to the start up costs of better equipment and juice. she also sent me a link to a utube video on how to refill and maintain the equipment. in the title it says DSE901....so i gather that is what she is sending me. who makes this model so i can look it up? can't wait!
