I recently got an e-cig from a friends who quit smoking everything entirely and didn't want it anymore. I know it's just one of those cheap ones but I'm a light smoker and it's been ok for me. I just want to know the model# of it so I can buy better cartridges from a different company if possible. It's about 102.*mm in length and 9.*mm in diameter so I'm thinking it's either a RN 4081, DSE 101, or DSE 103.
Any help would be appreciated. Thanks!
