[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.
[A]: Negative


[Q]: Does a great job highly visible. Works well with the different fencers that I use in the different pastures. Last a long time. Can't beat it for the price.
[A]: Positive


[Q]: Classic Jazz Piano was previously owned on a tape which eventually died I was pleased that the same much liked music was still available in cd not only as a download and at a reasonable price this will encourage me to 'up date " some more of my ageing collection
[A]:
Positive
