The PowerColor JustSling is certainly an interesting device. As one of the first commercially available systems utilizing WHDI, it does manage impress by pushing all the pixels you need. But you should consider the fact, that you will never reach the full distance advertised (much like with any wireless technology) as it only manages around 12.5 m line of sight at most - while PowerColor mentions up to 25 m on their website. That said, when it works, it does so without the need to set anything up at all and manages to offer lag free input through the included USB port or with the remote control. This means that PowerColor has done an excellent job employing the technology available today and the only thing really holding it back is not for a lack of engineering, design or trying, but simply due to the fact, that WHDI is fairly new and this is all one can tickle out of it at this time. While there are other solutions out there, the JustSling from PowerColor seems to be the only one capable of HDMI 1.4a and HDCP 2.0.
