I've read a few reviews on Amazon... um... is this worth purchasing?

Any advice, please.

Any advice, please.

Always brush your teeth after meals.

Many thanks for that... I had always wondered how to retain that minty breath freshness without compromising on the flavours of food I consumed.

More specifically.... any advice about this book's content?

Other than it's in words and that some of these words are used to form coherent sentences and others less so.

The three reviews on Amazon go from: It's excellent to it's ok to it's garbage.

Which would be the truer of the reviews?
