The new 'glowsmile' tooth cleaning device doesn't do much apart from vibrate, as it doesn't do any cleaning whatsoever.
The advert and proposed feedback are misleading, the instructions are poor and almost non-existent, and the extra money for the special blue cleaning toothpaste was a con.
However, I was open to trying something new, but not prepared to be conned out of almost £50 for the device and toothpaste.
