This is currently being used with my Alpine CDE 133 BT Car Stereo.
Works well for Ipod connectivity.(my Bt Audio functionality lost due to IOS6 update,Bluetooth firmware update required on my Alpine)
The length is ideal with my phone placed in the empty storage slot above my stereo.
Tight connection.(tighter than genuine cable)
Very cheaply made,especially the 'metal' connector which plugs into phone port.
The connectors were marked which may indicate the cable has been used before.
Rubbish for charging the phone.
This cable takes ages to increase even the slightest battery percentage on my 4s.
For my use its fine until I update my stereo, for charging direct from my stereo its rubbish.
I will update on how the charge performs when connected to my 12v socket via my Powergen usb.
