Victor, I suggest you join REFR discussion at Silicon Investor forum. You'll get the answers/feedback there.
Be aware of deceitful posters (short sellers and their hired hands) who more or less control this stock at the present time. You're lucky to buy this stock at the RIGHT time.
solar, be aware of the liars on this board. They are hired by the hedge fund who are stuck in a short position, impossible to cover without driving the price substantially higher. Go to REFR's web site and listen to the latest conference call. Ignore the drivel on this forum.
