I've been using them for a little over a week and they work very well for me. I would like to know more about them, like, who makes them? Are they CE2 R? or what? (I want to google the exact model to find relevent info/reviews etc.) All it says on LF's site is that they are "Standard 510 Clearomizers". I would also like to know if/how they can be cleaned. Anybody?
