Good. So this is my second product from this company (IOGEAR), the first was an older version with a small key and a large receiver. He left within 90 days of purchase. I sent it back and they covered it with a guarantee. It lasted a year. Since it was out of warranty they didn't do anything else for me. I saw an advertisement for this model and thought I would try this new model. My setup is in my bedroom, less than 20 feet from the TV to the cable box, but who needs an HDMI cable running across the floor. This new large transmitter and large receiver work, but not very well. the signal is NEVER perfect (like an HDMI cable). I connected both and played the same HD movie and you can see the difference. Forget 4K, you're lucky enough to get 1080p most of the time, and 720p drops to 480 at times. In my room there is nothing between the two transmit and receive antennas so it shouldn't be a problem. I have contacted IO Gear and since it "works", there is nothing they can do. I'm very disappointed with the performance, but it "kinda" works. Addendum: just bought new. Waste of money, hard to express my disappointment. 10ft in my bedroom, don't get a 1080, barely get a 720 most of the time. It crashes and crashes all the time. Both products failed.
