Daily Mail's Good Health section featured the AMANO;

It asked a Dental Practitioner, who specialises in bad breath treatments , to review our £12 solution (incidentally, he charges his customers £205 for the first appointment).

Not surprisingly perhaps, he was sparing in his praise.

He did admit this however:

"It's the most attractive tongue cleaner I've seen"

Bizarrely his advice was to; "hold your tongue in one hand and scrape it with the other".

That's not (we would suggest) a technique the Romans, Hindus and Victorians would have recognised (or George Washington perhaps?)
