First off, I think that the concept of this company is innovative and it will survive. Basically it's robotic surgery. Although I haven't looked in depth on how it works and such, it seems to be a service in demand. As robotics get more advanced, they will overtake humans in precision and efficiency.
Looking at the short term trend, it's not the best buy in. I am likely going to place a small bet in it and hold long term if it gets back near the 50 cent range again.
