Eight helmets that failed 2004 DOT testing

From the current Motorcyclist.

'Last year the two independent labs contracted to test helmets tested 42 models.
The eight that failed performance testing were:
MDS RC4 (for failure to adequately attenuate impact force)
Nexl 05 (for retention and penetration failures)
NXT 101 (for retention-system failures)
Rodia RF-2 Modular (for exceeding the single peak G limit)
Rodia RHD200 (for exceeding peak G three times and retention-system failures)
Rodia RHD500 (for retention-system failures)
Vemar VRX3 (for multiple penetration failures)
Zamp S-1 (for retention and penetration failures)'

Never heard of most of them, but beware.
