Like its sister Gemini-Hybrid, the BTB-100W is built in solid zinc alloy, the elegant design and it's very small shape make it comfortable and easy to hold.
The entire frame, excluding the removable panel, is, therefore, a single block in zinc alloy, at the top the section tapers progressively, connecting with the base of the 510 which has been machined to integrate in a very visually pleasing way into the overall design of the BTB. The 510 connection has also been quite cleverly raised to avoid scratching the edge of the mod whilst positioning atomizers and the floating pin 510 is gold plated and the connection thread has been designed to be very smooth during threading- all of this is really very typical of Lost Vape- who are really well known for their absolute attention to small details like this.
The compact design is paired with the large 4ml capacity UBX (Ultra Boost X) Sub-Ohm Tank, coming with MTL Airflow intake-adjustable airflow for DTL and MTL. It is designed to deliver if you are familiar with the Gemini Hybrid (upgraded version) then the expectations are already high and you won't be disappointed. It is also compatible with Ultra Boost Coils and is Suitable for high nic-salt e-liquid MTL. (make sure you have checked your viscosity as the thicker it is the lower your temp should be)
