Q: Paxton Quigley's book is a compliation of parts of other books on firearms self protection. It's a bit overdone, and probably would scare the average woman thinking about protecting herself. Women seem to have special problems protecting themselves. They usually do not want to hurt anyone, and they will do all most anything for a baby or a family member before they will do anything to protect themselves. However, women that are able to continue to practice with a hand gun, usually become quite proficent. They know that they don't know, and they listen to instructions. Most men think they know it all already.

A: Negative

Q: Purchased this to replace the OEM power adapter (puppy chewed it up). Works fine, does the job. A little bulkier than the OEM, and I would have liked the same type of LED system to indicate charging/fully-charged status. Still, for the price, it's just fine.

Positive
