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!

A: Positive

Q: I've been a longtime fan of Mercedes and own most of her Valdemar series. So, of course, I picked this book up at my local store. After wrestling through 50 pages, I gave up! I plan to sell it back to my local store ASAP- this is nothing better than a paperweight in my bookshelves. The worst part is, my boyfriend picked it up and tried reading it. Now he thinks that this is a good example of her work!

Q: There is no other way to put it. All Visioneers are garbage. Purchased my 2nd one (after first one died for no reason after a year) and have experienced many problems. Lately it won't let me scan anything because of an error saying to "unlock your scanner". There is no Freakin lock on the darn thing!!! After contacting the company many many times (btw - there customer service sucks! - No telephone number, unless u pay $2 per minute, just a computer-generated machine that unsuccessfully helps you called SARA). I finally put a claim in through the Better Busines Beaureau, there response was that they couldn't send me a new scanner cause it was after 1 year of my purchase, but they would be so kind enough as to let me purchase a new one and give me 25% off of their price (which was probably an elevated price). I told them to kiss off! Anyway - please don't buy this product or any Visioneer product - they Suck!
