According to an investigation by 2Firsts, since late September, several e-cigarette brands, including ELFBAR, SMOK, Lost Mary, and FASTA, have introduced disposable e-cigarettes with flavor adjustment features on distributor websites in the UK and US. These products typically come with multi-level adjustment settings, hinting at a potential new focus for market competition.
Previously, flavor variation in e-cigarettes primarily involved flavor-switching mechanisms, with many brands offering “rotating mouthpiece” models allowing users to switch between two flavors. In early September, the disposable e-cigarette Insta Max 20K 20000 appeared on multiple UK sites, featuring a double-tap button function that enables users to switch flavors or activate a mixed flavor mode.
Now, flavor competition is intensifying, with an increasing number of e-cigarettes offering multi-level and multi-mode flavor adjustments.
From higher puff counts to screen upgrades, from smart features to added hardware like “Bluetooth earbuds,” the disposable e-cigarette market is marked by continuous “innovation” in an ever-competitive landscape. The question remains: “How many more surprises are yet to come?”

Multiple Modes for Flavor Customization
Beyond different flavor options, each product offers unique methods for adjusting flavors. The most basic flavor adjustment uses buttons, allowing users to switch flavors by pressing or toggling settings. Another method, gaining popularity with larger screens—especially “3D curved screens”—is touch control for flavor adjustments. (Read more: The Rise of 3D Curved Screen E-cigarette Products)
