Design and Appearance
The XCube Crystal Kit arrives securely packaged, with plugs protecting the mouthpiece and airflow holes to ensure freshness. The kit includes the Crystal pod and the XCube battery, though you can also purchase the pods separately if you already own a battery.
The most noticeable change is the pod itself. It is now completely transparent, showcasing the massive coil inside. This clear design is a significant improvement over opaque pods. The rigid plastic mouthpiece is slightly broader than previous soft versions. It is now made of a rigid material, different feel from the soft silicone on the classic pods. But it still maintains an ergonomic shape that feels solid and well-constructed.

The XCube battery remains largely the same, but with new screen animations to differentiate it. The display clearly shows battery life, e-liquid level, and the selected power mode. Both the battery and pod feel sturdy. Magnetic connections ensure a secure attachment, reducing accidental disconnects.

Performance
The performance of the XCube Crystal Kit is a significant step up. Its new coil technology provides a noticeably cleaner vape compared to older models.
One of the best improvements is the redesigned airflow control. You can now dial down the airflow to a very tight and restricted mouth-to-lung (MTL) draw. This setting provides a punchy and satisfying throat hit that many vapers seek. Fully open, the airflow allows for a smooth, restricted direct-lung hit. This level of precision makes the Crystal Kit versatile enough for almost any preference.
Also, the large coil generates satisfying vapor production, especially at higher power settings, while still delivering good performance at lower levels.
The ability to use the pod independently while the main battery charges is a practical feature. The modular pod remembers settings even when detached. Users can continue vaping while recharging the main battery. Longevity will depend on chosen power level and individual use, but a fully charged battery can last a typical user most of the day.
Flavors
The Crystal Kit is available in a range of flavors. Most are clear and enjoyable, with reliable output from the improved coil. The taste is exceptionally crisp, clean, and consistent from the first puff to the last. We tested a couple of the available flavors to see how they perform.
Scary Berry
Crisp raspberry and blueberry notes. It delivers a vibrant and sharp mix of raspberry and blueberry. Sweet, slightly tangy, with a gentle cooling finish.
Blueberry Apple Cobbler
This flavor is a masterful blend of fruit and dessert. Balanced blueberry and apple with a subtle, dessert-like aftertaste. Minimal cooling lets the fruit flavors stand out.
