I can confirm it works without issue on the VW600ES. My initial impression is, well, I'm not really impressed. Netflix 4K is nice, but there is pretty limited 4k content. The Video Unlimited freebies I checked out left me feeling pretty lackluster. Upscaling BD on my 103D is in many ways just as good and there is better sound as well. Got a feeling this thing is being returned.
