I'm amazed at how this stock manages to hold up so well at these levels considering the buy depth. There have been on a number of occassions whereby it looks as though it's about to completely collapse due to lack of buying depth. But sellers appear patient and hence, buyers subsequently emerge again to hold up the SP at these levels.

From what i've read of trials from company's website, all looks good, but it does look fragile, any pullout by buyers at .14-.15 and this thing could really nose-dive?
