The Eleaf HW coils are already a popular choice amongst hobbyist vapers who love sub-ohm coils. But the HW-T2 0.2ohm use unique and innovative technology to provide a completely different vaping experience.The HW-T2 feature a mesh coil and organic cotton, with a massive difference. They have a small ‘turbine’ installed in them. This is there for several reasons, it creates a ‘swirl’ in your airflow to distribute it evenly, meaning optimal flavour from your e-liquid. It also helps to prevent any spitting, as any e-liquid drops are driven back into your cotton.
