I got this because it was listed before Christmas in one of those NZ Herald ‘Gift Guides’. It's a good price, too. At first glance it looks good, 75 projects to make, that's a lot, but many of them are out of your league unless you are wealthy or have an engineering back ground, while others are so easy as to be pointless. There are a few projects that could be downright dangerous or even illegal in NZ. Overall I enjoyed reading it, and there are maybe half a dozen projects I might try, but i was expecting more, though maybe I shouldn't have been for the price.
