I really haven't had any problems with my blu I get some big clouds and a lil throat hit with flavor.. And I don't really wait between puffs. still not always consistent but works good for me.
blu users, if you find you have to wait too long between puffs, it's because your cart filling is wicking liquid to the atomizer too slowly. This will happen with ANY e-cig if your liquid and cart filler aren't working well together; it just so happens that blu's clever-but-ineffective pre-filled carts have that problem out of the box.
To fix the problem, you need to replace your cart filler with something that wicks faster, and replace your liquid with something less... er... underwhelming.
I've had terrific success restuffing standard blu carts with both PET cut from Lipton Pyramid tea bags, and, most recently, with reticulated polyurethane cut from fish tank filter sleeves. If you check the
Cartridge Mods subforum you will find lots and lots of details.
And I've been very happy with liquids from Johnson Creek (the reduced-PG ones work better for me), Intellicig (ECOpure), and Decadent Vapours. The last two are all-VG and produce LOTS of vapor.
Be aware that restuffing carts is an art. The tighter you pack the material, the slower the liquid will wick, so thicker fluids need looser packing. Pack too loosely, and thin liquids will leak. There's a lot of trial and error before things start to click.
And don't forget about gravity. Seriously, once you have your carts wicking well, just holding the cig so that liquid flows from the cart to the atomizer makes a huge difference.
I'm using the reticulated polyurethane as a filler now, and my carts drain COMPLETELY before they stop kicking out vapor. I never need to wait between puffs.
