I bought this book awhile ago and I will say it's a good book for its price. It has big pictures which are really easy to follow and copy. The down fall is that it has so many positions that a lot of them are too crazy and hard to do. Some require a lot of flexibility and some even improve your flexibility which is a big plus! I haven't tried all of them by any means. I usually go through and just pick ones that look fun and interesting. I have learned many new positions that are a whole lot of fun!

The book has 365 days worth of positions each positions has a date which is a lot of fun because, you can go in order or just flip flop around!
My personal favorites would be:
the Stairmaster, The Happy Crash Test Dummies (very fun, except when you try it in socks on carpet, be careful you can slip!)

Crazy positions that didn't workout so well were:

The backpedaler
&
The Rising Tide (was not comfortable for me whatsoever! Ouch!)

I really enjoy the layout of the book with room for comments or notes at the bottom of each page. With so many positions it really helps me to keep track of the positions I really like or the ones that are too difficult or aren't so comfortable for either me or my fiance. As for the pictures, I don't care for them, they're just a little plain there's nothing to them. It would have been better if they used pictures of real people doing the positions. But that didn't have any damper on my choice to buy it anyway!
I also like how small the book is, it fits in my purse and I love to take it on get-aways with my fiance, especially when I want to surprise him! Since it is a position book I think that they could have added more positions for oral sex for both partners.

Overall though it's a great book to have to spice things up in the bedroom when you find that your doing the same positions in the same order every time you have sex. This is exactly why I bought the book in the first place and I've had so much fun trying new positions. It also gets you thinking about trying things you may just have only fantasized about that you're not exactly sure how it could work. I even find myself getting into bed faster at night because I get more excited about having sex and trying something new every time. We still use this book almost every night after having it for more than a year now and we wake up happier every morning because our sex life has really improved!
