I hope it's a lot sooner than a "few years off". I'm 78 now and have been a believer and investor in this company's tech for 13 years. I know Ron has been a believer and he isn't a spring chicken either. I don't think it will take that long to start producing revenue. They have the science, the design is done for a small device and they have the manufacturing all set up. I do believe the Uband is a few more years out but the KnowU box seems to be ready to generate some much needed cash. IMO
