question:
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.
answer:
Good Review


question:
The device works but after two months of use it broke and I ended up spending $30.10 for a new one from somewhere else. Not too satisfied since the first one didn't last that long. The only problem is I have to buy another.
answer:
Bad review


question:
This strap goes around your waist like it's supposed to, but can be easily adjusted. It's comfortable on my camera. Only one problem - if I'm shooting at dusk or in any kind of light you have no idea what's going on, so I'll need more than this.   Rating: 5.
answer:

Good Review
