although I love this forum, what works for one person another person hates...
I have a mod, but I still mostly use the egos/joye 510's I started with. most people here think they are horrible, but I like them & I have a lot because I believe in backups. I can't afford to be wasteful!
I carry 3 of the 510s around with me (in a cig case) so the short battery life doesn't affect me. I also use a cart similar to what you should get with your kit. yes, sometimes it floods my atty and sometimes it doesn't wick well, but overall it works fine for me.
vaping will require some fiddling with. don't expect it to be as easy as lighting a cig. most of us get used to it and find it worth it.
also, I don't always follow the way lots of people do things. I only clean my attys when they don't seem to be working well, I clean them as a last resort before tossing them. lots of people seem to routinely clean them.
there is a learning curve with vaping. these days we want everything RIGHT NOW (even the microwave is slow!) but you need to relax and try to not get frustrated.
also, lots of us vape and smoke in the beginning. it can help.
so I suggest ignoring what you have been reading about what you ordered and just try it when you get it. and fiddle with it til you like it. and then you may move on to something else. sell or give away what you don't like.
and liquids. only order small bottles until you have been vaping a while, your tastes will change.
you could look around the link below and see if there is going to be a meet near you, having people help in person is the best!
