I haven't tried the Blu, but I have read enough reviews of it to know it's a pretty generic, low quality product in the grand scheme.
however... I don't think that BT would get into ecig production just to put out terrible products to get people to come back. I suspect some of them may try that for a while, but I think in the long run what you'll see is BT getting into ecigs so they can firmly hold onto a market they have completely owned for a LONG time. They don't like there being a lot of alternatives, they don't like people buying from overseas, they don't like people being able to make their own, in so far as they can control any of that. I think the strongest thing we can do to keep the quality of products (equipment and ejuice) is to largely divorce the whole thing from the one place they have control, and where they will make the biggest push, which is regulation. If BT really throw their weight behind this stuff, they will most likely push to getting ecig equipment and "juice" (likely in for form of disposable ecigs or carts, not in refillables, because they can't have the same kind of profit margins) to stay regulated, how analogs are, that narrows the market and puts any of the potentially 100s or 1000s of small time competition out of business. I think the only way we can keep the ball rolling as it is would be by making largely 0% nic products, with a secondary market to buy high nic as needed as an additive. If all your favorite flavor places keep selling stuff with nic in it, it will eventually (maybe not for awhile, but it will happen) push them into a place they have to be regulated.
