[EX Q]: There is no plot. What in the world did I just watch? Nothing made sense, from beginning to end. I've lost my faith in humanity after watching this...

[EX Q]: Dear potential sucker,My first airbed by intex sprung a leak in about a week, so I obtained a refund. I bought this model next, and it lasted almost twice as long!I am now on my third. I should have learned my lesson, but my current intex airbed has been around for about one year, and currently has 9, count 'em, NINE leaks. Everytime I patch one, another springs.Intex also makes inflateable boats. They must get sued for a lot of drownings. No wonder they have no email contact. If you buy ANY intex airbed, you are buying utter garbage.Sincerely,SidWa State

[EX Q]: For the fact that the book was written just a few years after Li's death, information was fresh and probably quite accurate. I just wish that the book has a lot more photos. I enjoyed reading it.
