The Wenax Stylus from Geek Vape is an AIO pod device that is strictly aimed at mouth to lung vapers. It features a 1,100mAh battery, 2ml liquid capacity and either auto or button draw. There`s not a lot to the operation of the Wenax Stylus. It has two ways to fire, either with the button on the bottom or by simply sucking on it, and the auto-draw will kick in. The auto-draw works wonderfully well, and is really responsive.
