Honest opinion?
I believe it all depends on what the purpose of the video is, or rather, what type of customer are you targeting? Let me tell you why...where as I love War Pigs, though I've never heard that rendition, the video lacks proper instruction/demonstration of the product. Which is fine, if you're targeting people already knowledgable on the device and/or people already on this site, as it is a vault of information, should it be needed.
Now, someone who has never used an e-cig before might look at the video and say,"Wth is all of that?" So, were I to make a recommendation, however valuable it is or not, I would say that you guys should make a video with someone desribing briefly the product, the parts and what they do, and how to use it. Something along those lines.
