[Q]: This book was written in the 70's by a man who knows his stuff, which is a rare find nowadays. The problem with it is that he relies too much on anecdotal stories and anecdotical sources to support his hypothesis. It feels like reading someone's blog, not science. Also, some of the anecdotes don't make any sense unless you can explain away how they happened.
[A]: Good Review


[Q]: My mom read this series and we both have enjoyed them. Can't wait for more. Love the characters. Worth reading. Enjoy
[A]: Good Review


[Q]: I'm extremely satisfied with how much power this dual charger supplies. I have had multiple devices plugged in simultaneously on several occasions without any problems, including iPad chargers, cell phone batteries, Kindles, USB external disk drives, digital camera batteries etc. Great product. No complaints. Highly recommended.
[A]:
Good Review
