Nancy from Buffalo, NY reviewed Cloud 9 model 'CL9_501' on January 12 2012:
OverallI love Cloud 9. My Pulmonologist recommended it to me. I have smoked for 39 years, well over 2 packs a day. After a month of the Cloud 9 e-cigg, I am down to no more than 12 real ciggs a day. This is so UNBELIEVABLE! Never in a million years did I think I'd quit smoking. Had no desire. I will be totally off commercial cigarettes within the next month. THANK YOU CLOUD 9! AND their customer service is super. Response to emails is super fast.
