So when I saw this book, and the amount of pages it was, I decided it would be a pretty good buy.
And it is. You get around 240 pages with very few transformers taking up more then one page (Megatron for example takes up two pages, but I'm a fan of him so I was all too happy to see this!). This means you are getting a lot of transformers represented. Each guy has a nice full color picture and a smaller picture of what they transform into. The artwork is great for the most part, and I'm sure fans from all ages will spend a lot of time just flipping through the book and looking at the artwork.
I really liked how it goes into detail on a lot of the transformers presented, for example on some of the triple changers it points out that due to the amount of parts that have to fold out to create one of their bigger vehicle modes, the robot is very strong due to the condensed parts.
Also each gattai, or combiner, is presented as its own entry after a list of the robots that combine to make it, a nice touch.
I only had two problems with the book, and they are production issues.
The first is that some of the pages are darker then others, it doesn't happen a lot but it is a little vexing to have some nice artwork all darkened.
The other one, which is just me, being nit picky... On the left page in the background there are a series of 0's and 1's, but on the right page, these are backwards. Clearly just a flipped image but come on, someone should have caught that. (You may note the few "problems" I have with it aren't really big, and most likely will be fixed with other printings.)
I would love to see a hard-bound version of this, for as durable as it seems I really can't stop flipping through it.
This really is a great product, and for the price you are getting a lot of artwork with a decent amount of information. As has already been said, if you're a fan, or just getting into it, I highly suggest you pick it up.
