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:
All the features are nice, TV Guide worked (note that browsing and setting recording preferences is very SLOW), BUT when the TV Guide is downloading (all the time) or you are recording / playing from the hard drive you constantly hear a grinding sound from the hard drive. These guys must have used a cheap hard drive or something. I have the Amazon return slip on my desk......

Ex Output:
Negative
