I use this for my nintendo switch so I don't have to run a cable through the wall. It works well and was easy to set up. I've had no connectivity issues so far.

No funciono en elequipo de videoconferencias que queria funcionara

This works great in a small home or apartment. You would probably want something stronger in a home any larger. The connectivity is good. Overall a good value for the price.

I was looking for a solution to wirelessly cast video and/or audio signals via HDMI at home or when traveling to other indoor or outdoor HD TV's or monitors. This works particularly very well. It seems, but a few years ago, this technology wasn't as popular or yet perfected for consumers. This unit includes 1 each of a transmitter and a receiver along with 2 USB to USB-C cables, an HDMI cable, 2 attachable antennas for the receiver and an instruction guide. It is easy as plug and play. The transmitter has a built in HDMI short cable, while the transmitter you will attach the included HDMI cable or your own if longer is needed. The instructions suggest to connect the receiver first to ensure a stable Wifi signal, and then to connect the transmitter. They should easily pair, if not there are instructions to use the reset thimble on the receiver to set the connecting for pairing. Also for stable connections, you may need to power both the transmitter and receiver with your own USB power supply with the included USB to C cables. I only tried casting 1080 HD video and audio from my Windows PC and I was very pleased with how well it works with a stable signal within my home and in the back patio. I hope to continue enjoying the flexibility of easy wireless HDMI casting and hope this remains reliable long term.

This seems to be an older revision of another unit I recently reviewed (ASIN R3HI3OBW4JFHVZ), and has most of the same characteristics. It's physically bulkier with awkward antennas on the receiver box, and I couldn't get the firmware upgrade to work, so I'd strongly suggest going with one of the newer versions. The transmitter on this unit can be powered by the HDMI input cable, but the receiver MUST be connected to a USB socket. As noted above, the receiver is bulky with cumbersome antennas. I had no issues connecting 4K@60Hz *BUT* the units would not carry 3D (1080P@30Hz) no matter what I tried. That ended up being a deal-killer for me, but I doubt it's an issue for most folks. Do be aware that the receiver creates a WiFi hotspot and uses that for connection to the transmitters. This allows use of your smartphone or other device to connect directly to the receiver, *BUT* it also means you may have interference with or from the WiFi networks around you. You should be able to connect to your own WiFi network and upgrade the firmware, but on this unit I got an infinitely spinning wait symbol when trying to upgrade - which seems consistent with it being an older revision chipset. Installation was "plug and play" simple, when properly connected the receiver outputs a screen full of graphical and textual information to your display which goes away once a transmitter connects and provides a video signal. Despite good functionality, newer revisions are available at similar pricing without some of the physical and software issues, so I can only give this a 2 star rating. If you happen upon one at a bargain basement price, can handle the bulky receiver design, and don't need 3D then this is functionally a good buy - but not at the current asking prices.
