Works good, though the transmitter gets hot!
Works good, though the transmitter gets hot after an hour of use. Would be nice if you could just power off the HDMI vs using the USB cable as well (two more inches would be nice)
I just received mine and I'm watching a sports event with it. It works perfectly and it is so simple! You just plug it in and it works. No software and no batteries. Video and sound both work perfectly.
