I bought the adapter because my old Mini DisplayPort to HDMI Adapter is not working properly on my MacBook Pro (2011) under Lion. The error is known in the network. The old adapter has delegated under Snow Leopard Audio and video, but when I updated to Lion was no longer a sound transfer. I have tried everything to get the sound to run but nothing helped until I bought this adapter.
The adapter itself fits well with Apple and it looks good is narrow, really white, almost elegant.
It works beautifully with Lion and a MacBook Pro 2011 and transmits audio and video
