welcome aboard rwh01. I see you have been sent plenty on biel to make a decision on whether to invest or not. my only advice to anyone at this stage of the game would be to not sit this on the back burner too long before you make a decision on whether to invest or not. any day a pr could come out that could make this sp gap up a bit from present trip 8, very low entry price into a company that is in the process of changing the way we treat pain. the actipatch takes my back pain away much better than anything I have ever tried.
