Quite simply works in connecting our 'Camera-to-Video Switcher' over distances beyond the HDMI length restriction ... although have had to replace a few of them over time. Have now turned to 'Active HDMI over Fibre Optic' , although opinion as to which is the best option can only be made over time to see how long the Active HDMI holds out vs the LENKEN HDMI Extender kit. But as stated ... simply works right-out-of-the-box.
