Negative Positive
Title: The worst investment for my technical studies!
Review: I was looking for a good book for my thesis related with Foundation Fieldbus, but I was dissapointed when I received this tiny pocketguide. The relationship between cost & benefit isn't advantageous for the buyer. ...with no extra information than what you could find on [their website]. If you want to make a good investment, this is not the best item that you could acquire.
