[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]: I wish I could rate this camera -9999999999999999999999999999999. Actually what I really wish is to mound all of the Vivitar Vivicam 55 cameras up in a pile and BURN THEM. Anyway, I found this camera at Walmart thinking it should be good for the $20 price tag they were asking. When I first opened this wannabe camera I noticed the buttons were very cheap. More than half the pictures taken were either blurry and/or yellowed. Don't bother trying to create a video with this thing unless you like a still frame video. I brought it back after I did some research and found the Logitech C310 Webcam for several dollars more here on Amazon(which has HD!). This is the worst camera i have EVER used. Live and learn, and never buy anything made by Vivitar. Shop around and spend a few extra dollars for a better camera. If not, you get what you pay for.
[EX A]: Negative

[EX Q]: A first rate beautifull compilation, with every selection a winner. One of my personal favorties. Great music and great soundinf too. Ella's "Spring Can Really Hang You Up The Most" was for me, a revelation. All artists best work.
