Ed from Mount Union, PA reviewed Vapor King model 'VK etank stainless manual' on September 25 2011:
OverallI bought my Vapor King etank a little over a week ago after using the Safe Cig for almost four months.
Value vs. Cost
I ordered the stainless steel color etank model w/ auto battery but they sent me one with a manual button battery.(note that this is exactly the same model battery regardless of what their site might tell you as on the original Vapor King model because they do not show a stainless battery color or atomizer as an option for the etank model when buying parts which I did buy as backup parts)
I am actually very pleased that they sent me the manual battery type (alot more freedom and control over your drags).
I would definitly recommend also purchasing the charging pack as well. With my usage, I get about three hours to a battery at a time.
