[EX Q]: I used this program for my science class. My students loved it! They learned some interesting facts, saw damage from earthquakes we talked about in class and never once did I hear that it was boring! Can't beat that!
[EX A]: Positive

[EX Q]: I orderd this magazine in August... There should be some type of notation telling customers that it takes up to two months or more befoee the first issue will arrive.......What a waste of time. I could have gone to the library and received this magazine for free to read......I am still wating..... and there is no tracking number, therefore you just don't have a clear date for the arrival of the magazine.......not happy right now,,,,,,
[EX A]: Negative

[EX Q]: The product did what it was "supposed to" which was to give me a waist, but it kind of just redistributed my fat. My waist was super tiny, but above and below (mostly below) I bulged like crazy, so I ended up just looking really oddly proportioned. My husband thought that I looked a little like an arthropod, so definitely not the sexy curvy lady that I wanted to be... I guess this product worked for other ladies, but for me, it just looked really unnatural and odd.
