[Q]: This case is made of VERY cheap plastic. It broke while I was trying to get it on my ipod. The plastic breaks easily and can be taken off. DO NOT BUY!!!!!
[A]: Bad review


[Q]: This item was advertised as having a "quick connect." I have had the product for less than 18 months and when attempting to remove it, it broke in half. The plastic is extremely brittle. You would think that if this were part metal with metal threads, a plastic knob or button connecting them together could hold up better in light of some reviews, but you know what they say about assuming- don't assume.
[A]: Bad review


[Q]: This book is a must have before you take your first step on learning the theory behind game theory. I found it lacking in depth - but then, I'm neither an astrophysicist nor mathematician. It was nonetheless very interesting to read and get some idea of what goes into making AI successful. Of course, playing games are required for this. After all, we don't expect robots controlling robotic drones to play chess either. Even so, it's a great reference work which should help anyone who wants to further their understanding beyond games.
[A]:
Good Review
