Ex Input:
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 Output:
Positive


Ex Input:
A tiresome meander through bits & pieces of ancient history and philosophy to try to prove, once again, that there is a great effort to keep humans from realizing their potential and the secret wisdom that was revealed in former times. Dull, pedantic and unfocused.

Ex Output:

Negative
