[EX Q]: I purchased the Intex airbed to replace an Aerobed that our cats "loved" too much during a guest visit. Comfort wise, the Intex wins hands down-supportive yet comfortable as well. Convenience wise, it inflates a little slower than our old Aerobed (albeit, there is more to inflate) yet it takes up less room when rolled and stored in the sack that comes with it. The only reason I didn't give it 5 stars is because it is VERY high, so a restless sleeper can fall off pretty easily.
[EX A]: Positive

[EX Q]: This set of assorted short tracks is hard to avoid if you want to create a track layout of even an intermidiate size. The male-male and female-female pieces will provide a dramatic increase in the number of layouts possible as you can now overcome the problem of curves returning to the starting position.This is a must-have for any Brio enthusiast.
[EX A]: Positive

[EX Q]: This movie was a horror film thhat displayed an effort to steer clear of typical horror movie dialogue and pacing. There are no blonde girls and the girls that are here don`t trip over the tree roots in the yard. Now a white girl did fall and twist her knee in the movie but guess what? It was not on a tree root!!!
[EX A]:
