Hi! 
  
I'm new to e-cigarettes too. 
  
I started at the start of the year and it's been a hard transiton after smoking regular cigarettes for  years. 
  
There are numerous review site out there and most have been very helpful in introducing the different brands out there. 
  
I found this review helpful: (spammy link to affiliate site removed) 
  
I think it's basically trial and error plus word of mouth! 
  
I'm glad there's forums out there that can help guide us!
