Has its purpose fully met.

I have this bag for 2 seasons in use. He was as a supplement
about Ortlieb panniers for dry transportation of light tour utensils
(Sleeping bag, clothing) purchased on the bike. This stuff sack
has the Praxisttest fully passed. He has kept my things absolutely dry at wolckenbruchartigen rains. Also use
the bungee cords to attach to demGepäckträger he has survived without damage. However, I recommend the bag nich to cram too full.
One should have the rolling shutter 3 windings treat in order to ensure the tightness.
Conclusion:
There are certainly better but also much more expensive stuff sacks.
For the above purpose, it is sufficient.
The value for money is ok
