[EX Q]: I bought this air mattress to use while my new bed was being shipped from back east, the bed lost air every night and I woke up almost on the floor. I tried to send it back but it was impossible to get back into the box.
[EX A]: Negative

[EX Q]: I purchased 2 of this item as Christmas gifts for 2 of my grandsons. They have both watched it more than once and have thoroughly enjoyed it. I did not have any problems with my order. It was received in a timely manner, and in the condition promised.
[EX A]: Positive

[EX Q]: Don't let the sleek look of the emarker fool you, it's got bugs a-plenty and some serious design flaws. Here's what the other reviews (written by Sony employees?) and the literature don't say:* E-marker doesn't seem to work with AOL; you have to not only use another browser, but also set that browser as the default.* When you plug the emarker into your computer, it "automatically" loads your marks into the site...or at least that's what it's supposed to do. On 3 browsers and 2 different computers, I haven't quite gotten this to happen.* Sony seems to be more concerned about being cool than functional - to top off all the emarkers' inadequacies, they (over)designed a Flash interface to get your songs that doesn't quite work either. Simple HTML would have been fine, guys....Spare yourself the agony and wait for version 2.0....this is the first time I've been irate enough about something to write a review and I assure you everything above is true...
[EX A]:
Negative
