Featuring only one button, the Caliburn X is easy to get on with even if you've never vaped before. You can use this button to switch on your kit, select a power level and start vaping. When you're done, lock the kit by pressing the button five times. When unlocked, you can also vape by just inhaling on the mouthpiece. This inhale activation plus the small amount of vapour the kit creates means the Caliburn X feels a lot closer to a cigarette. At the same time, the mesh coils also mean you'll experience a better flavour. Easy to refill and capable of holding up to 2ml of your preferred e-liquid, the Caliburn X pods feature a top-filling design with snap-fit lids. This means you can top up your pod without actually removing it from the device. Speaking of e-liquid, a small window is also built into your device so you can see exactly how much is left.
