I lost my favorite 510 atomizer a few months ago. Since then I have been kill atomizer after atomizer. The vapor production goes down after about 2 weeks to a slight wisp. I use the fluid I always have and still nothing. It has been frustrating me to no end. I am about to give up on the 510 and start looking for a new device. But every time I get a new atomizer I am reminded of how much I love this device and the massive amount of vapor it has the potential of producing. Has anyone else been having this problem? Any suggestions? -Devon
