Great Point! That SGLB is different than others in the space. It is pure luck that we are able to get a piece of the company. I thank the guy(I have to dig the name out) on some other board who made me look at this 8 weeks ago! I am happy that I got in although a bit late it doesn't make a difference when it goes over $5! Anyone who is still on the sidelines: It is still not late to buy! Good Luck!
