Just got it in the mail. I tried the cartridge that came with it and it was too low for me. I didn't really feel anything. I also got high camel liquid with it. I'm done with this cartridge but i'm not sure how to fill it up. Should i just put some liquid straight in the cartridge or what. By looking at the cartride, there's almost no cotton stuff in there. In there rest of the cartridges there is more cotton. How should i refill this? And there's a little hole on the atomizer. I'm not supposed to cover that right?
Thanks.
Thanks.
