Greetings my teachers. I debated on where to post this, here, General discussion, or new member. I decided here since I am using the 510. (Mods if you feel elsewhere is more appropriate please feel free to move.) OK...every time I feel like I get a handle on vaping I get new a dilemma. I want to beef up my 510 a bit. Seems like an ego batt is an option but that is another chunk of cash to get a couple of batts and a charger. I also know I need more atty's and that is where my new confusion of choices comes up. I get atty vs lr atty - LR = greater heat = more vape. Please correct me if I am wrong. So, I guess my debate is between buying regular atty vs a carto. I looked around for info on the carto but none of the guides I found really discusses it well. So, please let me know if I am wrong on what I have gathered. The carto seems to be a cart and atty combined. Looks like that are supposed to be one time use but as always there are mods. People pop off the end (mouth piece end if I am correct) and can drop in 20-30 drops. Seems pretty similar to a regular cart. Am I missing something here? So, what is the difference? Since the cartos seem to be much cheaper then a regular atty I assume that means they are supposed to be disposable, at least more so then a regular atty. So, turning over attys more often means you use fresher attys. But I read a lot on cleaning regular attys and people can make a regular atty last a long long time; especially for someone like me that does not chain puff the atty. Does a carto deliver a better hit then regular carts? Why is one better then the other. I am sure personal preference will play a big part in this but any and all comments on the atty/cart vs the carto would be much appreciated. (And if you know a good thread that already addresses my questions please feel free to post that link. I don't want to reinvent the wheel but I looked and couldn't find any posts that cleared away the fog.) As always, thank all of you for your time and patient answers.
