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

Koontz can write. But he sucks as a story teller. Books are supposed to have a COMPLETE story in them, no? Well this one has no ending. No end at all. These 2 detectives are clued in to the fact that Dr Frankenstein exists, and is creating his "perfect race" to some day kill off all humans. That's it. You meet the original, now educated and "at one with the universe" Frankenstein's monster, you meet the main characters, and they have some conflict. That's the whole "story" in this book, which it really isn't because the basic elements of a story are a beginning, middle, and end.

I purchased this product just a few months ago and it's broken already. It was used at a desk with ear phones so it wasn't moved,bounced or anything you would expect a personal player to withstand.It skipped at the slightest bump and went through batteries like crazy.I now have a different CD player and would not recommend this to anyone.
