[EX Q]: THIS AIR BED IS GREAT! I HAD PREVIOUSLY PAID WAY MORE FOR THE "A--O" BRAND, BUT THIS ONE IS EVERY BIT AS GOOD AS THE MORE EXPENSIVE ONE. I AM A GAL WITH A "MATURE" FIGURE, AND IT (TWIN) ONLY LOST A LITTLE AIR. WITH THE ELECTRIC PUMP, NO WORRIES! JUST A HINT FOR SOME OF YOU WITH BAD KNEES LIKE I HAVE....I PLACED TWO CAMP COTS SIDE BY SIDE AND LAID THE MATTRESS ON TOP. PERFECT FOR THESE TIRED OLD KNESS AND BODY TO GET UP AND OFF OF. KUDOS ON THIS AIR BED!
[EX A]: Positive

[EX Q]: The book I downloaded on my Nook and Kindle doesnt seem like the same one I read in school. This version Bored me to tears.
[EX A]: Negative

[EX Q]: This CD looks to be a 9 track version of the Howlin' Wolf Live Gold CD (Fine Tune 2212-2) which has 14 tracks and appears to be available through Amazon Marketplace (the first nine tracks are in identical order on both CD's). From listening to the samples on Amazon the sound quality of the 9 track CD appears to be the same since as the Fine Tune version. The Fine Tune audio quality is not all that good, may not really be live, but it is the Wolf, after all. Thought fair warning was in order.
[EX A]:
Negative
