Best advice I can give you....
Look up reputable vape shops in your area. A good shop has folks who love to vape and love getting people switched over as best as possible. They should be very knowledgeable on vape gear (whether they carry it or not). They should ask you a few questions to figure out what you need for your current smoking habit and if they don't carry it, can usually direct you to where.
Getting started can be trial and error, so don't give up right away. It's different from smoking, but can really be a life savor for you. Here at ECF can be a wonderful source of info and people who love to help you along the journey. As mentioned above, everyone is different and has different needs and wants.
Lots of luck to you!!!!
