Their goal was to create an easy and intuitive Mouth-to-lung (MTL) replaceable coil-head atomiser for either the experienced vaper or the new user who wants a no-fuss system. The Zlide features a super-simple sliding top cap making topping up the tank simple and quick with the drip tip acting as a child-proofing system in that it needs to be pulled out to open the sliding top cap. The coil head can be pulled out from the bottom for a clean and mess-free coil change. The air flow adjustment is a twist ring at the base with a wide range of different settings to suit your needs. The coil head for the Zenith range now includes the new Plex 3D Mesh 0.48? as well as the original 1.6?, 0.8? coils and the Plexus 0.5? so you should find a head to suit your preferences. The Zenith range is quickly becoming the gold standard for MTL vapers and the Zlide design adds some nice improvements.
