I recently purchased some cartomozers for my SD. I am using a 901 to 510 adapter but the ends are not right. Are there male/female cartomizers??
Both ends if my SD and the cartomizer are females and they won't go together. Do i need another adapter?
Please tell me what i am doing wrong. These cartomozers are made to fit the 510 right?
