Got the book as a birthday present. Very dissapointed that it's only 40 pages. I thought it was around 150 pages and way overpriced. There are better books on the market. If you can't find a well reviewed one pass this one. I'm trying to return for refund. Really feel scammed. Thanks Amazon. :/

Bad review

I am a very visual learner and have to read the steps carefully in order not to mess something up. As you proceed along with building it becomes clearer. It is hard without photos explaining every step but that can lead to frustration. The final result shows some fine work, but I'm sure one could accomplish just as good results using the Internet or free web sites to find directions
