1. They’ve ditched the “cartridges” for better “tanks”
An e-cigarette is basically two things: a battery and a container that heats a flavored, nicotine-laced liquid into a vapor. In older e-cig designs, the latter part included a small piece of cotton, which would absorb a portion of e-liquid to be vaporized. But cotton always retains some of the e-juice, and makes for inconsistent drags (causing the last few to be harsher). Now, the blu Plus+ product line uses a cotton-less closed-system container called a “tank,” which lets you vape down to the last drop.
2. And they got the actual inventor of the e-cigarette
That's right. Hon Lik, the Chinese pharmacist and inventor of the modern e-cigarette, is now working with blu. Every e-cig on the market today relies on the basic design of his OG prototype from 2003.
