Company reply - would not supply clinical report , why not? have they got something to hide. Why not place it on their website so one can have some confidence on its claims.
There is a market for such a device but how many sports people would buy such a device. Do i think it works as well as claimed , no . Its a gimmick.
A report that implies such nasal dilator devices are not for athletes. I would put Breathe-Assist in the same boat. Athletes claims are baseless and used for promotion when hard evidence rebuffs such claims.
