Design and Build Quality

The Uwell Caliburn GZ2 boasts a compact and stylish design that sets it apart from its predecessors. With a blend of aluminum metal and high-quality plastic in its casing, the device strikes an appealing balance between aesthetics and practicality. The auto-draw system eliminates the need for buttons, making it user-friendly and convenient. The ergonomic design ensures a comfortable grip, making it suitable for extended vaping sessions.

The LED lights and light strips on the device add a visually captivating element to the overall design. The LED lights up in various colors when drawing on the device, enhancing the vaping experience and creating an engaging visual display. The device's ability to vibrate and light up when the pod is detached from the battery adds a touch of sophistication and attention to detail.

The top-fill design of the pods makes refilling a breeze, eliminating potential messes. However, concerns about pod leakage and the durability of the snap-off mouthpiece are worth considering.


During testing, the Uwell Caliburn GZ2 demonstrated impressive performance in both flav and vapor production. The device comes with two pods and offers coil options with different resistances, allowing users to customize their vaping experience. The 0.8ohm coil excelled in vapor production, generating dense clouds and adding a visual element to the vaping sessions. The 1.2ohm coil, on the other hand, delivered exceptional flav performance, providing a delightful burst of flav with each draw.

It's worth noting that the device seemed to struggle with fruit flavs compared to cream and dessert profiles. This discrepancy could be a subjective experience and might vary among users.

Equipped with an 850mAh battery, the Uwell Caliburn GZ2 offers impressive battery life, allowing for extended vaping sessions. The inclusion of USB Type-C charging support ensures fast and efficient charging.
