The only thing positive about Blu is that for better or worse, their juice is indeed garnered toward a healthy vape - Johnson's Creek Juice. Blu's cartomizers though are a universal ponzi scheme because they're designed to burn their own filler material, which is unhealthy, and their kits break 6 days later. If Blu specifically sold top-feed clearos and Ego style cigs like Johnson's Creek does, I'd have no problem with them actually. They just need to get their gear in line and stop ripping off customers.
With Johnson's Creek's ties to Blu, I surely would not think Blu would try to run Johnson's Creek out of business. But maybe they would. I don't know. I'd hope that Johnson's Creek would somehow get a bypass when it comes to legislation if it ever happens - I'd probably be able to live with their devices and juice, I do like their juice. And while it's way more expensive, surprisingly, I'm getting so much a better vape from a local shop's Clearotank and regular old Ego battery.
It's mainly too that Blu's ecigs don't have overcharge protection. Even the website says the voltage can range up to 4.2, and that's unsafe for cartomizers. Which is why theirs probably burn up so much. But Blu's customer service is actually very good. They have warranties lasting a YEAR. They also offer points refunds for burnt cartomizer packs if you just keep asking. I didn't even go through with it because I started to dislike the company, but hey, for better or worse, they're somewhat trying. They're being greedy though with those horrible burnt cartomizers. They need to invest in better technology, but they don't want to spend the money, so they probably want to put everything else out of business.
Also, one thing: if the government ever says that flavors have to be limited to tobacco and menthol, it doesn't really change much. You can put a banana flavor in and label it as tobacco. As far as I'm aware, there's virtually no way that the goverment can officially judge what tobacco is supposed to taste like in a juice. I'm sure it'd be more of the underground shops manufacturers that do this, but they'll get around it most likely. And 0 nicotine juices and flavorings cannot be regulated as far as I'm aware, unless propylene glycol turns to a controlled substance.
