Through Amazon, I came across the above boxes, and can now get rid of first reports.
Pro:
+ Stable boxes - they do not bend, are clear and properly processed
+ Freezing and * deleted * microwave safe * / deleted * (see below) 1a passed!
Conveniently +
+ Totally waterproof and odorless - here comes through anything.
Cons:
- Here I could only run, that more than one handle is necessary to open a box (because they are closed on 4 tabs on each side). But that does not bother me really ... function before design.
Conclusion:
Super Parts - low, and just for the "initial set" ideal; I had only accessed once and not buy these cheap boxes from the supermarket ...
* Update 23.10.2011 *
I have the boxes now in use for several months, and am still satisfied with the workmanship and quality.
Also, I have found that they are partially sold to a larger electric market, and have since taken me 2-3 containers.
However, the "microwave strength" seems to be not quite given. I had a pasta bake in the micro heated in one of the boxes, then eaten and washed away the can. And I have "the dirt does not get off the walls" until I've found that this is apparently to "scorched plastic" is.
This is me but so far only one of the boxes happens - maybe too hot and heated for too long, no idea. In any case, I see by prolonged heating in future have - the boxes retain their 5 stars, because they are just great :)
