The Geekbar 600 range features a powerful 500mah battery that has the capability of creating up to 600 flavour-filled puffs from the 2ml tank inside. Vibrant coloured devices within a crystal-style jacket house the magic inside. Flavours include energy ice, which brings us a lush soda drink synonymous with the original along with Lemon tart that creates a taste of tangy buttery biscuit goodness. Advantages include not needing any accessories or peripherals, all you do is remove from the packaging and vape, and once it's empty, throw it away, and grab another. They're also a sealed system so there's no leakage or tanks to fill.
