Tim Harford's writing style is very accessible, and takes some of the mystery out of economics. I would recommend this for those with a passing interest in economics, but it is also thought provoking to those amateurs who understand, or think they understand economics.
I bought this as I alwys have trouble getting a streak free finish when I wash the windows. So far I have got very good results with the Karcher. The only thing stopping a five star review is the price. At £10 less I would have awarded 5. Overall it has met my expectations.
