[EX Q]: We had to buy a new lunchbox for our son after 2 months (a different brand, machine-washable) because this one is way too hard to clean. I have turned it completely inside out, scrubbed between all the cracks, and still food is stuck in the seams andthreads. It is very durable, but we can't get rid of the smell or stains with a reasonable amount of effort.
[EX A]: Negative

[EX Q]: first the acting was so so so bad the movie, this is what i have to say ?but they get E for effort.
[EX A]: Negative

[EX Q]: I purchased this less then one year ago, already the buttons are less responsive. The biggest problem that I have is that it does not play the songs correctly any more. I can hear the music and sometimes the back round singing but not the main singing. This started out as a periodic problem as I was running but now is almost all the time.I am very disappointed in this player.
[EX A]:
Negative
