Dude,
The market is saturated. E-cigs and vapor pens are commodity products, produced in mass quantities,very cheaply,by a wide variety of producers, with very little differentiation in product.
USEI cannot survive on these cheap commodity plays, and very unlikely this company will achieve its lofty promises. The expectation of failure is reflected in the stock price. Glorious press releases, at most, provide a short term bump,but the stock quickly sells of again.
