4K Wireless HDMI Transmitter and Receiver Kit - 5G Dual Band 820FT Range, Ultra HD Streaming for Home Theater, Gaming, and Presentations (Black)

I wanted to test some HDMI transmitters because the idea is pretty cool.This pack has a case and a transmitters / receiver pair. They are 1.2" x 2.6" x 4.5" without the antennas, adding the antennas adds another almost 2" making the unit 6.5". The have the option for a battery pack, but this set doesn't come with those. the body of the units has a 1/4" thread for a tripod/mount on two sides. The antennas must be removed to be put into the case.These are pretty cool. My use case was that i wanted to watch a movie from my xbox but that is in another room on the other side of my house. I was able to plug this into my xbox and play a movie to my TV in another room without issue. There is definitely some lag in there, so gaming would be tough (maybe turn based). The audio and video were only the slightest bit off, which didn't bother me while watching a movie.What i wanted to really test was the range, being able to use this on a projector outside could be cool. So got in my car with my laptop connected to the transmitter. I connect the other side to my tv and put a camera to watch my tv from my phone. The transmitter was able to send a signal from my car through the wall of my house to the tv from 140m or about 460ft, and that is impressive.I like how the units feel (the top is metal (probably for cooling) and the sides are palstic. The 'industrial' look is cool and the case is a nice touch. I like that they use USC-C for power.
