I too am a newb here. I'm not even a smoker...

My wife is, or was, or something to that effect.
We bought a Blu, and haven't been pleased at all with it. I can get a pretty decent vapor out of it for a few drags, but then it stops performing. She has a harder time than I do at getting a good hit off it at all (she's used to "analogs")...so ironically the non-smoker has had to teach the smoker.
Anywho, Here's my take on the Blu
Battery life - poor
Vapor production - inconsistent, and not very impressive
Atomizer - I'm not sure what it could do much better, as It gets hot....
I think the problem is two fold - Battery, and the carts. On the battery it seems that it produces its best hit when its right off the charger, each drag afterwards is less powerful. On the carts the foil was a bad idea. I'm sure if we were to mod it up we could make it perform reasonably consistently. (we will try refilling carts and dripping once fluid arrives)
I will say that the carts we ordered from Volcano did produce more vapor more times before crapping out (estimating 20 instead of 10)
She only smokes when she drinks, so the PV and all associated bits stays in the kitchen, It seems that if you take a drag or two then put it down for 10 mins and come back it will perform better than if you were trying to smoke the equivalent to a cigarette at a time.
At this point it looks like the Blu will be going back. We have a 510 coming from totally wicked to see if its any better...I know they aren't the cheapest, but she saw the pink...and she likes pink a lot. I also ordered a sampler pack from Awesomevapor.com so we can try dripping/refilling...
We are both still learning, and I've spent about 20 hrs on this forum searching and reading over the past week (I decided I might as well register today).
I actually like the taste of the menthol (which to me is Mint) that came with the Blu, but I can't tolerate much of any of it (I assume its the nicotene that makes me feel jittery). I'd enjoy one of these without nicotene, but that might just be silly....so haven't decided if I'll order me some nicotene free juices.
