I once made the reversal test with ice:
Alfi: filled, after one hour, a puddle of water in the container,
the GGS to this: no water, fresh as from the chest, the ice is even a little each frozen.
I always einpacke the Bergner in a small cloth bag, I ntl. no problems with scratches.
& Costs z.zt. one third less.
so thats it...
