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.

A: Positive

Q: Over the winter, i seem to gain alot of weight. As a high school quarterback, that is not acceptable. Last summer, i think i went from 160 to 150. That's my gross weight loss. I'm not even talking about how much fat i lost. I gained a good amount of muscle over the summer, so i probably lost over 15 lbs of fat. I got my six pack back, and life was great. After the season, i just quit, and now my six pack is back in the fridge. I'll probably order some up next week and start again. These are great, and the results are amazing.

A: Positive

Q: I thought this book was the worst book ever. It was so boring! Did I mention that it was the WORST BOOK EVER!!!! It was the worst book in the history of bad books. You should never read it. Take my word on that. Oh, and I didn't just choose to read it on my own. A teacher forced me to read the dumb novel. IT'S THE WORST BOOK EVER!!!!!!!

A:
Negative
