Ex Input:
This was my first attempt at a diet or exercise book. I bought it in paperback for the price of only $3.99 and thought I'd give it a try. The format itself is easy to follow, though there isn't enough detail on each recipe -- if you don't know where to start, as I didn't, it's pretty difficult getting back around to it. The actual recipes themselves are not that exciting. I've made them several times since receiving it; they taste alright, but nothing too special.

Ex Output:
Good Review


Ex Input:
I don't know what to write here, this product didn't work at all for me. It was a complete waste of time and money. I tried it on one eye first, the light did not affect my eyeglass frame or any other part of my body whatsoever. To conclude just dont buy. I will probably never be able to find something else that works. Save your money - there are plenty others out there. I wouldn't suggest giving this little cheap thing even 1 star but you have to.

Ex Output:
Bad review


Ex Input:
I felt like the author wasn't paying much attention as so many recipes start with a large amount of meat and/or eggs in them. This didn't appeal to me at all. Don't waste your money unless you can bring yourself to read every recipe. They sounded good, but they were all just too much.

Bad review
