I haven't taken my exam yet...but from what I reviewed in this book, I can say it is well written and covers all the material needed to get a passing score. I received this item at a discount in exchange for my unbiased opinion.

It looks and feels sturdy and I like the esthetics of it. The only thing that bothers me is that I can fit my credit card, my ID and my subway card there but whenever I need the one that is not at the very top, I have to take all 3 out as there isn't a way to just slide one out. Overall, I'm satisfied and I would buy this product again. The shipping was fast and reliable.

There are so many different variables that come into play when 3d printing but through using IC3D's filament, this is one less variable to worry about. The quality and consistency of this filament is the best that I have experienced and is well worth the added cost.
