The difference between NB and brava is that brava works on a lower pressure over a longer period of time per session (you have to wear it 8 to 10 hours per day) and NB can work on just a 30 min session once per day, but most like me wear NB for an hour or two per day sometimes in multiple sessions per day. But many think that brava works better because they do have case studies and scientific proof it works. I'm sure if case studies were done with NB it would be the same. Some say the brava domes are better than the NB ones because of comfort levels, I wouldn't know. But to me the main difference between NB and Brava were the price tags and time commitment lol.
