The information here can seem overwhelming. I'm only one week into this but already feel more comfortable with it all. I read the info threads and random other threads for a couple of days. I finally decided I just had to take the plunge and pick a model, then take it a step at a time from there.
The Joye 510 seemed a very popular choice, so I went with that. Get a starter kit whatever model you get- that will get you a deal on 2 atomizers, 2 batteries, some pre-filled carts, and an AC charger (more stuff if you opt for a fancier kit). And grab some sample liquids with it at the least. I went through cignot.com, a site that is well thought of here. Good prices and very fast shipping.
I was pretty much a chain smoker (40-50 cigs a day). Or at least a chain burner (you know, you light one up and next thing you know, your cig is one long ash), lol. Vaping is a bit different experience (I do take a lot fewer hits then I did with cigs), but it didn't seem to take that much adjusting to for me. And it's certainly less wasteful! The trick is getting the nicotine level that is right for you (I am using 25-26mg, but could probably go a little higher) and mastering the art of the vape.
I was having some trouble getting good, consistent hits and tried the straw mod today. What a difference! So if you have any trouble, there's no doubt a solution to be found on this board.
