Input: Consider Input: This is nothing new from Gail Howard, or at all. These wheeling systems can be worked out mathematically, without paying for this book. There are also lots of websites that offer number generators and wheeling system explanations for free. If you want it all spelled out for you then buy this book, but if you are willing to do a little mathematical work check out lottery information website like [...].

Output: Negative

Input: Consider Input: I was extremely lucky to have found this, because it is a) an import & b) limited edition...especially lucky to find just thrown in the kylie section of a Pennsylvania Borders! Ok, here it is track-by-track:1. Chocolate [Radio Edit]:While this cuts the album version of the song by one minute and two seconds, it's better. Her vocals are improved, & more of an arrangement is used. 10/102. City Games: THis extreme rarity is fabulous. Very R&B; pop. 10/103. Chocolate [Tom Middleton Cosmos Remix]: A club dub. Cool when you have so much energy in you that you have to dance it out, but not for a regular listen. 7/104. Chocolate [EMO Mix]: Woderful. A good R&B; dance mix of the song. 9/105. Love @ First Sight [Live]: A live version of the Fever hit. I usually love live sounds, but this when isn't quite up to par with the original. 8/10I still have yet to figure out how to access the video. (...)Overall great package, great mixes, great rarities.

Output: Positive

Input: Consider Input: Product is as shown but they didnt have it in stock and it took them almost a month to ship. And then instead of sending next day to compensate they sent it regular mail so it took another week to receive. Not too happy with their customer service.
Output: Negative
