The Kanger 3TS is similar to the old T3 with a very nice advantage...... It has a separate, replaceable bottom coil like the Pro Tank & Evod. So you can just change the coil without having to replace the whole base like on the T3. This makes it much cheaper to replace coils! The unit looks & functions great on eGo batteries and it has a 3ml capacity. The bottom coil allows you to vape every precious drop of your favorite e-liq without a dry hit. You don't have to tilt and and turn it when your liquid is low like on top-coil models. Also...for fellow chain vapers like me......no more burnt tasting hits due to slower wicking with top coils. The draw is very easy and the vapor production is excellent. The new T3S is not on the website yet but I'm told it will be soon. I definitely recommend this product! Happy Vaping!
