If you are in the US, there are no bands in use here that haven't been used in other countries for years. So it's really quite safe to use a "new" band.
As for the radio controlled one, I've been watching the various clinical trial websites and there doesn't appear to be clinical trial going for it just yet. The FDA only recently approved it to go into clinical trial so I assume they are setting up the programs now. So it shouldn't be too much longer.
