Sorry, but I can't believe Made in Germany. Not for this very low price and not with ventilation mockup etc.
Schuberth helmets (really Made in Germany) are >=400€ and everything does its job.
It is crazy, but they are. Here is the manufacturer
http://www.speq.de/They are TUEV tested, ECE-R 22.05 compliant, visor is FF-803 compliant.
Helmets are my favorite topic. Nobody EVER managed to explain to me the difference between 50, 100 and 200 EUR helmet and back it up with objective tests.
If you showed me this helmet 10 years ago, I would say it is in 300-400 EUR range.
