Works perfectly without special configuration

Once the drivers and other software installed, works perfectly on the first try without any special configuration.
Requires USB3 Port (cable), and a powerful enough computer to encode the video because the case is no encoding (relays the video stream crude, which explains its price 2.5 times cheaper than other boxes of video capture USB3) and a HDMI splitter if you want to keep an output on a screen other than the computer because it does not have HDMI output.

My setup:
- Wii U Console HDMI output
- HDMI Splitter HDElite: input connected to the Wii U, output to the display output to the capture box
- Case connected to a laptop ASUS G750JW (i7-4700HQ processor, graphics card GTX 770M, 8GB RAM)
- Acquisition of video directly from Open Broadcasting Software, both for broadcast and on Twitch for registration, which is responsible for the encoding.

The video delay on the computer is so low that I can play with the TV off while watching the preview on OBS.
