I've been vaping exclusively for approximately 2 1/2 months. My only experience so far has been with the eGo/TW Tornado. I love them for most of the time. Just recently ordered a JoyE Stick for occasional discrete vaping. I have seen several reviews on it, but have found the information to be a bit iffy regarding the atomizer. Some reviewers seem to love the atomizer that is included with the Stick, while others think the included atomizer is lacking. I'm afraid I'm still too new at this to even know which atomizers can be used with this device. Is there anyone out there who can tell me how to determine which atomizers would fit in this device and, perhaps, enhance it's use and vapor production?
