Yes, thats about it with a two piece... but all ecigs can be quirky and/or unreliable at the most unforgiving times.
With the two piece, sometimes a cartomizer will fail, or the carts arn't "full", as well as those batteries with auto switches can be the most unreliable things, not to mention that sometimes they can go off with the sonic pressures experienced in the club scene (which is why I now only have a manual switch device).
But I do understand your preference as it was also mine in the beginning with the Smoke51.
Whatever you decide on, you should really consider the customer service, the location, etc, should you experience any issues (which are a pain in the .... if your ordering outside of Canada due to customs & shipping).
I haven't came across a reliable vendor in Canada for the two piece is all, but of course I don't presume to know "everything" (<--- don't tell my wife, lol)....

thanks for the info! i must admit i'm still trying to get my head around all of these terms people are using on this site for different brands/models etc but i'm confident i'll be able to make an educated purchase after a little bit more reading. doesn't really solve the lack of reliable vendors for a 2-piece in canada though
