Here's how it works in plain terms. A coil is basically a wire that gets hot when electricity passes through it. The heat turns the e-liquid into vapor. If the coil heats unevenly, you get weak vapor or a burnt taste. Mesh coils solve that by spreading the heat across a larger area. Dual mesh takes it one step further by using two layers, so the heat is even more uniform.

What does that mean for you? Mostly, it means better flavor and smoother hits. You'll also get denser vapor, which some people prefer. But there's a trade-off: dual mesh coils use more power, so your battery might not last as long. If you're a heavy user, that's something to keep in mind.
