Is this product review positive? Title: Cheap, Fast, Good! Review: I use lots of lenses and have three different XX-to-EOS Lens mount adapters. To protect them I purchased this cap. It goes on the EOS end (obviously) and protects the chipset for the assisted focus feature.When I purchased this item the total cost with shipping was under $5 so I don't see any reason to complain about price - to me it seems a veritable bargain - I probably should have ordered an extra or two at this price!Update:Be Careful - I ordered more of these (From a different seller) and received "fake" Canon caps. The ones I received are NOT made by Canon. They are very similar and even have "Canon" stamped on them. However real caps say "Canon Inc." inside and indicate the country the cap was made. The fake ones I received were not in Canon packages, had stickers hiding the "Canon" name (from customs inspectors...) and did NOT have "Canon Inc." and country of manufacturer stamped on them. Buy from legit camera dealers if you want the real caps... Answer:

Is this product review positive? Title: A Field Theory Textbook Like no other Review: Finding a good field theory textbook is one of the harder tasks of people's lives - but Itzykson's book is truly incredible. Starting from the very beginning, it develops the operator formalism with the Dirac equation, moves onto perturbation theory, then onto functional methods - and then to asymptotic methods. It's truly comprehensive.However, it's strongest selling point is the fact that it actually works out examples in incredible detail - where else do you find a complete computation of a two loop vacuum polarization amplitude? This is the ideal book for someone who actually wants to learn how to do calculations in field theory.It has two shortcomings - it was written in the 80's so it isn't very modern and it has no problems. But those pale in light of its advantages. Answer:

Is this product review positive? Title: Memoir/Spy Mystery/Excellent! Review: As a "Reporter" Richardson latest book is both erudite in writing and researching. As a person, I can highly relate to his "search" as someone whose father was a 3 War Vet for the Corps of Engineers... as my Dad said, "First In and Last Out". To me, contrary to an above review, Mr. Richardson is not really trying to clear his father of anything... he was trying to learn about someone he loved very much... for good and bad. It's about how often during that age we grew up with parents which often we know so precious, and I do mean precious, little about. It's seeing our own flaws and theirs... may the days of "Secrets and Lies (film directed by M. Leigh)" STOP!A Memoir isn't about accuracy nor heroism...it's about love/understanding life. My wish is no one go through that. Thank you for this book John H. Richardson! Answer:

Is this product review positive? Title: Wonderful Review: Sinclair Ross is a brilliant writer. Although this story deals with a loney preacher and his wife during the depression era the trials they go through are easy to relate to. I would recommend this book to any adult wanting to discover how to really love and forgive. The content matter is a little advanced, so I would suggest it for anyone sixteen or over. Answer:
