I know right! there's a huge selection of vaping gear out there and the only way to know what will suit your needs is to either try it(which could be very costly) or read what others have posted on sites like this and take their advice as subjective, were just getting a vape meet together for Edmonton and my hope is that after seeing what other people are using in person it will help me decide which products will be best for me before I shell out the cash and order them. Right now my biggest concern is that my main pv doesn't fail before I get a back-up device, lol
