First, you fill them with a syringe and a needle. They usually sent a plastic flexible looking device with the clearomizers that they tell you to use to fill them with. good luck on getting them to work. I found that a 20 guage needle and a 1 mm syringe works best for me. They can also be taken apart and cleaned and reused multiple times. I have some I have been using around 3 weeks now....still going strong. And I am a heavy vaper.
The boge also can be re-used several times but after a while they won't hold juice anymore and start to taste nasty. If you are happy with the Boges for now, just keep reading and watching some of the videos. ECF has mounds of info. I must say I wasn't prepared to the education I would need to aquire in order to vape. It is a whole new industry with lots of growing pains but well worth it.
