[Q]: I've bought several air beds from various manufacturers. I bought one identical to this one 1 1/2 years ago. It was comfortable but lost air after 3 months. I justified this as the user may have not taken care. However, I now believe its the brand. This one would not inflate at all. I will not buy this brand again. I've had great life from a better brands.
[A]: Negative


[Q]: I had placed a huge order for my children for christmas. I was so upset when my children got the movie and there was no disc at all. so my bad review is with the company not with Amazon since they were kind enough to fix this problem and send another movie free of charge and free of shipping!! Thak you!
[A]: Negative


[Q]: I disliked this DVD because close to the end of the movie it was all defected or scratched up and I did not get to see the end of the movie. I mean it was Jerry Lewis, so I know there were some good laughs at the end. So disappointed.
[A]:
Negative
