Vabeen pitches the Flex Air Ultra 6000 as about two weeks of vaping for an average user, which lines up with its 6,000-puff rating. That's a fair estimate for moderate use, but it's worth saying the heavier you vape, the shorter that window gets. It's built around a mesh coil, so the flavour stays reasonably smooth and full rather than dropping off partway through. The small LED screen shows battery life and e-liquid level, which takes the guesswork out of when it's getting close to done. The body is compact and boxy, easy enough to keep in a pocket. Nicotine is 20 mg/mL salt for a smooth throat hit. It's a middle-of-the-road disposable, nothing flashy, but the screen and mesh coil make it easy to live with day to day.
