I was wanting something like that too a while back when I first started
vaping. I know people have talked about it elsewhere on the main forum but I'm not sure anything every came of it. Someone was even going to make a wiki of all the models and give more info about them. Perhaps a "wiki" search would turn up something.
The thing is, IMO,
ecig use is so subjective to the actual user I think it's kind of hard to put something like that together. I'm more or less talking about the pros and cons. It would be pretty easy to write a feature set but other than that I'm just not sure how reliable it could be.
Another monkey wrench to throw in there is the knockoffs in our industry. That being several companies making the same ecig model and it gets even worse for the spare parts which ultimately is the whole ecig as the parts die off. Sometimes you end up using an ecig made by several different manufacturers.
That is one of the reasons some people get frustrated and give up on
vaping. It may sound off but the better solution might be a comparison list of manufacturers and stating exactly who sells and makes what.
