Vapouriz Clear Tank Clearomizer This is, by far, one of the best Clearomizers available in the market today. Suitable for the Vapouriz Tank, or any device with e Go/510 connection. Why is it so good? * Leakage is non-existent * Flavour is exceptional * Throat hit is superb * Not only that, replaceable wicks (heads) are available at only £2.99 each, avoiding having to replace the whole unit. Instructions: How to Fill The Clear Tank is filled by turning upside down, & unscrewing the base of the unit. It holds 2.0ml of e liquid, 25% more than standard CE4 clearomizers. Then proceed to fillinside the clearomizer whilst upside down, taking care NOT to get liquid in the inner hole. When liquid is at the 2ml mark, replace bottom & attach to your battery. Make sure the atomizer/head is screwed on tightly to the base. They do not come pre-tightened & will need to be prepped each time they are filled. If you are finding liquid seeps out into the middle barrel, this is why. Simply unscrew & tighten the atomizer/head & you'll have the best vape you've ever experienced! Video instructions coming soon.
