First, congrats on the decision to Vape instead of Smoke, it truely is a Life Changer.
2nd, don't panic. The Blu does work. But you have to understand and accept that the Blu (and all PVs) are not the same as a real cigarette. You hvae to drag on it a little differently. Don't just suck on it hard and quick directly into the lungs.
Instead, draw on it slowly into your mouth (like drinking soda from a straw), draw it into your mouth for just about as long as you can, then remove the ecig from mouth, then inhale.
It will take practice, but this is how to Vape.
A good way to judge if you're sucking too hard or not hard enough...
It will take practice, but try to suck on it just barely hard enough to keep the LED light on.
Also, you are right, the prefilled cartridges from Blu are....not great...
First, after you put the cart on the atomizer, take it right back off.
Take a paperclip, and bend one of the ends out.
And use that to push the inner part of the cart out.
Stick the paperclip right through the little hole on the mouth end, and push.
Remove as much of that foil as you can from the inner cart (and from the atomizer).
Then push the inner cart back in, and put the cart back on the Atomizer.
Then look at the forum suppliers link here, and you'll find a TON of suppliers of
ejuice.
Start refilling your carts. But don't use the stock polyfill that came in them.
There are plenty of better materials. Personally, I use the PTB
mod.
I've been on my Blu for 2 weeks now, not a single analog since 4/26 5:30 PM.
Hope that is helpfull.
