[EX Q]: Product was defective from day on and lasted a whole 32 days and now will inflate but by the middle of the night you sleeping on the carpet.
[EX A]: Negative

[EX Q]: I love my Zen Xtra 40GB - well at least I loved my Xtra. The player is great, except for one major detail - the shoddy quality of the headphone jack. IT WILL FAIL! If you get lucky it will still be under warranty. If you aren't expect to pay at least $40 for the clowns at Creative to fix it. If you think I am just flaming them, check out their forums.
[EX A]: Negative

[EX Q]: I used the search window using "3-d movies" as the criteria and this movie popped up along with dozens of other 3-d movies, but when I received it, I realized I had not read the description close enough to see that this movie was NOT 3-d. Amazon-please don't place 2-d movies selections in with the 3-d ones! I had to pay $2.98 to return an item that shouldn't have been offered in a search of 3-d movie selections. Ouch. All in all I love Amazon, but I'll be more careful in the future. My bad.
[EX A]:
Negative
