I picked this up because it has the details for technology faults and radiation hazards that I, as a GM, wanted to get ready for in PFS season 6.
As far as the value of the book goes, PFS legal-wise, you are only going to get about a dozen pages of content out of the 68pg book.
There are 6 feats that are legal, including Technologist (a must for season 6 skill monkeys) that gives you access to expanded uses of Disable Device, Heal, Kn: Arcana/Engineering/Geography for interacting with technological devices.
There are about 12-13 new spells with technology themes; however, 2/3 of them are just re-skinned existing spells (Protection from Tech, Magic Circle Against Tech, Detect Radiation, Remove Radiation, etc.)
Three of the five archetypes are allowed: A cleric that can channel to heal/harm robots, a rogue that replaces magical trap abilities with technological trap abilities, and a barbarian that str/dex rages and has firearm proficiency. The only prestige class, Technomancer, is not allowed.
The rest of the book is filled weapon/armor/wondrous item descriptions. About 95% of the weapon descriptions start with "This extremely deadly..." ... blah blah blah. None of these items in the book are legal anyways. Though I have to admit that I am exceedingly disappointed that the Sonic Screwdriver, er, e-pick, is not legal... but here's hoping for one on a chronicle sheet!
Overall, worth a couple bucks, but for PFS legal content, it's severely lacking in yummy goodness.
