Wireless HDMI Transmitter with 2 Receivers, 330FT/100M Long Range

They are well built devices, and include all the accessories you'd need except USB power adapters - which you may not need and the trend lately is to not include them because of the EU laws. But it does include a USB A to C cable, about a 4 inch HDMI extension cable, and HDMI to micro-HDMI adapters. They come already paired from the factory so there's no need to try to pair them. Two receivers, but they will support up to 4 receivers. I haven't tested the full range but I did test through three walls and about 25 feet and it was perfect. A couple of downsides, but nothing show stopping: * It won't work with 720p input or output. 1080p and 4k only. When I connected the receiver into an old 720p TV it just said "Not supported" on the screen. Not surprised, but don't plan to use that old 10 year old TV in your basement with it. * It won't let the remote TV/monitor go to sleep when there's no image transmitted. It just plays "check transmitter source" on the TV. That's a bit of a problem for what I had planned because the PC would turn off the HDMI output at night, but the remote TV's won't turn off when it does, but they will if they are connected directly by cable. It'd be great if with no source input it just stopped putting an output to the remote TV but oh well. But I did test both receivers at the same time and had two remote images that were perfect. It also transmitted sound, which was in sync with the video. All in all, well worth the money. Simple to set up, literally just screw in the antenna and plug them in, and away you go.

Given there were some bad reviews I was a little nervous about ordering these units, but I find they do what they are supposed to do and work fine in my application. They came already paired with each other, no setup needed, and I judge the advertised range of 100 feet with an unobstructed path is honest because I'm transmitting about 55 feet from inside a cabinet and through a couple of house walls with a solid signal, no dropouts. Lag is essentially undetectable. One comment: Be sure to take note of the fact that each transmitter and receiver needs its own 1-amp "wall wart" USB power supply (or equivalent 1-amp rated source). These are not included, and while their description/advertising does mention this, it isn't prominently put forward and might come as a surprise. They do, however, include the needed USB cables to connect to the power source. Still, I give them 5 stars.

These are great for around the house or if you have an event and you need the monitors/projectors/tvs to accept a remote signal from the tech booth. They have a fantastic range if you have line of sight (like with most conferences) but also work pretty well if you have obstructions (like walls in your house). I've used these and the previous versions for mission critical work at different conferences and neither version let me down. These are a must-have in my toolbox. The latency isn't the best you can get from equipment that is hard wired or wireless costing thousands of dollars... but it's not bad latency at all. It is VERY viewable. I've seen much worse from broadcast organizations when it comes to latency. These are worth every penny. Always have these for emergency use or for when you just don't want to run hard lines everywhere.

bought this a few months ago, they came paired and worked fine for a couple of months. power got disconnected and sync got lost. now transmitter very hot, enough to blister and distort the plastic case and i have to keep it away from anything flammable, and receivers won't sync, keep searching. transmitter has solid light. receiver keeps blinking. tried resyncing according to instructions multiple times. transmitter defective/broken

So far, so good. Worked right out of the box. Just plug and play.

OMG, I couldn't wait any longer to write my review! I bought my wireless extender on Friday and it arrived today, Saturday, at 9:00 AM. EXCELLENT! 🥰 I hate cables, and in my opinion, this is spectacular. I can watch my programs on the TV in the living room, on the monitor in my kitchen, and on the TV in the backyard. The signal doesn't drop, and the signal delay is maybe one second, which isn't bad at all considering the distance. I'm very satisfied with the purchase and I hope it lasts a long time and I don't have any problems in the future.

Works great allows me to move to different tvs to play my ps4 with out having to unplug my ps4 and move the console itself. Love this item 🤟

They work great but both the transmitters and receivers need to be powered through the hdmi port from the PC source and TV receiving device. The older model transmitters did not require an additional usb power cord. The newer versions units now require a power usb cord and will not pair with older firmware units of the same model.
