[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!
[A]: Positive


[Q]: The product seemed like a good idea but wish I had read all of the reviews before ordering. The product is not sturdy at all. It didn't come with the number of screws noted on the instructions so I had to go out and purchase more in order to finish putting it together. That was after I spent way to much time trying to decipher the instructions. Also, the clips that hold the bag to the frame are very tight and very difficult to put on and remove. I've torn every bag I've used. I hate wasting my money; but, I'll have to buy a better one.
[A]: Negative


[Q]: The packaging was coming off the back of the package and the box it was in was distorted. I wanted to give this as a christmas present but it doesn't even look new!
[A]:
Negative
