I love how this product makes me look in my clothes!!! its shapes me into a perfect hourglass! i dont know if the claim that it permanantley reduces your waist after 30 days is true because i havent had it that long. my only complaints are that it is a little too short, so i still have a small bulge over the top in vthe back and i think it may be stretching out as i wear it as oppossed to it shrinking me, but overall, it is the best shapewear i have ever purchased. i love it and would recommend it to anyone.
Positive

This was the biggest waste of money ever created. If you want to know the song that much, call the station and ask them, they don't mind, really.

I have several photography books that I have had no desire to read from cover to cover. Then I found this one! This is by far the best photography book that I have laid my eyes on. I am reading it cover to cover and plan on reading it again. John Garret has written it in such a fun, simple way that really makes you understand photography. I've even learned more from this book than I have in a photography class that I have taken.If you are just getting started in your photography adventure, I highly recommend this book!
