It's Nice And Shiny And Everything. And Seems To Work OK In General. But The Latency Is Just Too Much For IMAG And It Was Unusable For Us. I Suspected This To Be The Case Before I Bought But Was Hoping It Would Be OK, But It Just Wasn't It Probably Works Ok If You Aren't Doing Live Video With It Returned To B&H
