Thanks for all the advice

This is one of the things that confuses me. Is it ok to refill the cartomizers? Is it ok with the company? If I refill should I make sure to get the sealed batteries? Is it easy to do? If you can just keep refilling them, then why do people buy so many additional empty ones? Ack...

Yes, it is ok with the compAny. Smokeless image even has a video on their own website showing you how to do it.

It's very easy. I have a video teaching an easy method .

You should always used sealed batteries. The unsealed are old technology.

They are still disposable. After a while, they go bad. They clog, get gunked up and burn out. Depending on the juice, you will be able to refill 5-25 times
