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: I have been buying Hi-Tec for years. When I found the Altitude IV I fell in love instantly. This shoe fits great, has little break in time and still holds its sturdiness as it ages. Well recomended.

A: Positive

Q: Well, on the plus side it has great sound and good picture the ability to expand the memory and an FM radio(iPods don't have this feature). The downside it that the screen has a somewhat greasy look. This doesn't show very much during movies but it is a bit annoying. The screen scratches very easily so I would reccomend a case. When watching a movie, sometimes the whole thing freezes up and you have to turn it off and back on again. This is not horrible but it does get on your nerves after a while. The spin wheel is awesome ( I like it much better than the iPods because the spin wheel actually moves on the Sansa View). The whole thing is very easy to use and very user friendly. Overall this is a good product.

Positive
