Review on CABLEDECONN Thunderbolt Mini DisplayPort DP to HDMI VGA DVI Cable Converter Adapter - Multi-Function Cobra Appearance for MacBook, Surface Pro, Air - Black by Patrick Johnson

I used this product for a business presentation. I used an HDMI connection and the video worked fine, but I never managed to get the audio to work. My colleague let me borrow a connector here (from another company) and both video and audio worked over the same HDMI connection. So if you're using an HDMI connection and don't need audio, it works. However, if you are looking for sound, I cannot recommend this particular product.
