“I have seriously 15 different cartridge batteries and concentrate pens, but when it comes to using my wax atomizer attachments the Ego-C Twist was my first and still is my first choice. By far works the best with my wax atomizers and is also great for truly "killing" a cartridge. I love mine (I've had many due to severely heavily use not at all due to poor quality and I have like 5.(Yourhave a few back-ups)”
