A woman's hilarious Amazon review for a pair of leggings has gone viral after she posted photos of herself 'rolling and sliding down a mountain' without even the tiniest rip - having even prompted others to recreate her situation to test them out for themselves.

Many of us find it hard to know what to say when we leave a review online, often feeling too polite to say anything other than a bright and breezy comment about great value or fast delivery.
