Let's cut to the chase — flavor is where the Caliburn G3 really shines. Uwell's Pro-FOCS (Flavor Optimizing Core System) coil technology has been refined over three generations, and it shows.

The flavor from the 1.0Ω mesh coil is genuinely excellent. It's clean, clear, and well-balanced — every note in your e-liquid comes through distinctly, without muddiness or harshness. Fruit flavors taste bright and vibrant, dessert flavors are rich and creamy, and tobacco flavors have a smooth, natural quality.

What impressed us most was the consistency. The flavor stays the same from the first hit to the last drop in the pod. There's no drop-off in quality as the juice level decreases, and we didn't experience any dry hits or burnt taste even when vaping down to the last few drops.

The 0.8Ω coil produces slightly warmer vapor and a bit more vapor production, with flavor that's just as good but a little more intense. It's a great option if you want a slightly looser draw and more vapor without stepping up to a full DTL device.

Compared to the Vaporesso XROS 4, the Caliburn G3 has a slight edge in flavor clarity and purity — especially with complex e-liquids with multiple flavor notes. The difference isn't huge, but it's noticeable if you're paying attention.
