My old man is a retired mechanical engineer. he helped develop this technology more than 10 years ago for hospitals for dosing. The technology is now 10+ years advanced in terms of accuracy, speed and ability and will now include biometrics technologies. I've been in DEWM for years now because of low risk on investment and upside potential. In the last few months it seems that my gut will be paying off over the next few years. Patience isn't for everyone :)
