Well, I don't think its target audience has been buying and reviewing it

This book seems to have been a disappointment to many who read it, though it is mostly because these people were not the intended readers.

This book is really written for people just getting started or thinking about getting started with online poker, or poker in general.  It has several chapters that cover the very basics of online poker, including something as seemingly simple as how to download and install the software.  If you already play poker online, this book will not improve your game much.  It is, unfortunately for many of us, really designed for BEGINNERS.  I would have found its information much more useful if I'd read it within the first month I started playing.  After playing for over a year, much of its information was already commonplace to me.  Picking up this book at any experience level will probably improve your game SOME, just not nearly as much as some other books out there.

While Doyle Brunson is an authority on poker, his expertise just doesn't really come through in this style of book.  Again, this is a decent book for those just getting started.  However, if you are already an OK player or have been playing for a few months, you will probably want to skip about half of the chapters.  There are some decent tips and strategies revealed, but just not enough to warrant a reading of the entire book by any kind of intermediate player.

I don't disagree with some points here, but overall it's simplistic.
Maybe that was the point. I'd recommend people take a look.

Hmm.. I think somethings missing here. This is the reason for my low rating. Its not necessarily the product, but the product fulfillment.

Cool, but I purchased this and I don't think it's coming.

I can't add anything to the reviews here.  People that should read it, won't.  I can hear critics whose favorite wild ideas are challenged by Sagan, saying How does he know I am wrong?  Sagan makes it pretty clear it is because they do not really know very much about the real world.

Most reviews for this book are not Amazon verified purchases.  When you read the book you will realize why.  In the book, the strategy is put forth for one to offer discounts in exchange for good reviews.  I'm quite sure that is what most of these non-verified reviews are doing.
The book itself did not have any new strategies that have not already been expounded many times elsewhere.  I could find no new material.  I didn't feel it was worth the time.

This is an odd little product that seems to have a very limited audience. Too bad because for that it's an expensive toy. For the most part, it duplicates what an iPhone or iPad can already do. The manufacturer seems to play up the capability of using it for two-camera shoots. Like I said, the market is pretty specialized.

There are a few good semi-technical reviews on this so I won't just repeat them verbatim, but rather add a few observations of my own.

It's nice that the hard case turns into a little monopod and that it can actually be used on a real standard tripod.  It's not nice that the camera swivels on a little magnet attached to the case ... but it's far to easy to bump it and knock the camera off. It doesn't appear to be capable of withstanding a few falls to a hard surface like pavement.

The little light is nice but you better be very close to your subject, otherwise it's just not bright enough.  It's nice that it's wireless but I wouldn't think of it as a sport cam. And the camera itself is surprisingly heavy for what it is.

There were a few reviews bemoaning the fact that the camera is useless with a PC or Android product. To be fair, that fact is stated clearly so if someone does not have a compatible product, they shouldn't buy this cam. That being said, I think Logitech is living in an unrealistic world by making this thing 100% incompatible with anything but Mac products ... virtually all hardware is multi-platform anymore and in the real world by far the highest percentage of people own multi-brands. I can see (for technical reasons) why functionality might be limited, but it makes no sense to not even be able to plug the USB into a PC and use it as a webcam. And WiFi is WiFi ... the signal should be receivable by ANY product that can pick up a WiFi signal. People want to carry smaller and LESS stuff with them, not larger and MORE stuff. The logic of making it 100% incompatible makes as much sense is not being able to use tires made for a Chevy on a Ford.

It is not as useful for me as I would like, but I should also say that I'm not studying it very diligently.

I believe it is priced too high for what it offers. While I didn't want any "frills", I was a little surprised at how little it does have for the price.

This book is not from my point of view - - -
I think it was the advertisment that compelled me to buy it.

The kids didn't really seem that interested. But I'm giving it 3 stars because it's not the writers fault that they weren't paying attention.
I received this product at a discount but this review is solely my opinion and the information provided is based on my personal experience.

It isn't what I was looking for.  I don't want to bother with starter, etc.  That doesn't mean someone else wouldn't like it.  I'm going to donate it to a used book store.

I found the popcorn to be OK.  I'm not as impressed as others who have reviewed it.

They haven't bothered with it, I thought it was a good idea

Not bad for its genre, but it's not true that it's a whole new way to approach weight loss. Not dieting, adding exercise, and using spiritual support have all been out there for decades. But if you haven't seen any of these, it might be a decent introduction. Just accept that you might need more inspiration for the years it takes to adjust to and really live with any big change in eating and movement.

Sort of just an excuse to put a veneer of fantasy nonsense on modern day items. There's a thing that replicates an ATM, for example. It's okay, not exactly what I was expecting based on some of the other reviews I have seen of it.
