For me, the length is sufficient and I would even air. Therefore ok.
Corner adapter transmits / stops.
Small Goodie (LED Keylight) has found its place on the key ring and makes surprisingly good services. (Thanks for the dealer)
When the transmission rate I can not say anything. Had never HDMI and I hate consoles. So I could really exploit neither quality nor rate. Operate an Apple TV over. Second cable is still looking for a purpose.
