The Caliburn G3 has one of the most natural MTL draws we've ever experienced from a pod system. It's tight but not restrictive — exactly like drawing on a well-made cigarette. There's no airy or loose feeling, and you don't have to pull hard to get a satisfying hit.

Unlike the XROS 4, the G3 doesn't have adjustable airflow on the pod itself. The airflow is fixed and optimized for MTL vaping. For pure MTL vapers, this is actually a plus — Uwell nailed the draw perfectly, so you don't need to adjust anything.

However, if you prefer a looser restricted DTL draw or want to fine-tune your airflow, the lack of adjustability is a downside. The 0.8Ω coil gives you a slightly looser draw than the 1.0Ω, but it's still more MTL/RDL than true DTL.

Both auto-draw and button-fire work flawlessly. The auto-draw is responsive and fires immediately when you inhale — no delay, no weak hits. The button has a satisfying click and is great for more precise control or when you want to pre-fire the coil slightly.
