[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]: The best thing I found in this book is the picture on the cover. Well, actually the uncropped version in chapter 5. Beyond that, I found everything else to be non-practical from a design perspective. A photo of a filthy dust collector area when discussing the advantages of central collection or electrical wiring that would never pass inspection is typical. I'd rather see plan views of real shops that work with reasons for the decisions made.
[EX A]: Negative

[EX Q]: If you've been wondering if our species is ascending or declining watch Transformers. If you haven't been wondering, I would like to take this opportunity to pose an ironic question, "What is it like to be mindless?"
