[Q]: Great American classic that you can get for free on kindle. I was supposed to read this back in high school but wasn't not interested at the time. But now with the benefit of age I can really appreciate it.
[A]: Positive


[Q]: The bed needs air refilling more often than I thought it would- every 3 days at the most. So much so that if I didn't pump it, the bed would all be like a water bed with "jelly-like" feeling. To lessen this effect I situated it in a corner of the room against the walls. Further more, what surprised me was the round water condensation on the bed sheet just underneath my (head) pillow in the morning. But what confuses me is that in the evening the bed feels cold (or the air inside feels cold).What I like about it though is that the pump works real fast in inflating- although it is loud for an evening activity.
[A]: Negative


[Q]: Just got this Blu Ray and just found out there is no DTS sound unlike what the description says on Amazon. Wait for the better version!
[A]:
Negative
