As per another thread on screen mirroring, I'm seeking a screen mirroring device that doesn't require navigating via cellphone, and/or an app. I came across the device noted in the title of this thread. Has anyone used it, and if so, how effective is it? It's basically a wireless device to device (transmitter to a receiver) setup. I'd love to see experts in Tom's Guide evaluate it, but will happily appreciate anyone doing so. I'd like some user or experienced input before spring to buy it.
