The cameras have not fitted our head unit and the seller already was honest and skeptical about it; once our head unit supplier found that he returned the cameras to this supplier who was cooperative. Although they delayed our refund till the end of the grace period of Alibaba (15 days) and were insisting on us to cancel the dispute (which we didn’t for official reasons) yet we are satisfied with the full refund they finally sent. Again it wasn’t the supplier fault that the cameras haven’t fit our head unit (which needed RCA cable and the 3D needs actually special device to do the algorithmic stitching and reconstruction of the 360 images into 3D). We haven’t tested those cameras to see them in action so we cannot comment on the image quality nor 3D, if any. Thanks.
