Wireless HDMI Transmitter and Receiver 4K Kit, Full HD 4K Wireless Presentation Equipment HDMI Adapter, Plug and Play Streaming Media. Laptop, Dongle, PC,PS4, Smart Phone to HDTV/Projector 165FT/50M

So far so good. This was plug and play and was working right out of the box. There did not seem to be any lag with the video or audio. I only tried it with a direct HDMI connection did not use for any casting. The quality of the picture was as advertised. Overall, after a month's use I would say this is a pretty good product.

This product is exactly as described and has worked flawlessly for us. We’ve used it for everything from streaming videos from a laptop to a TV, to karaoke nights—and it’s never let us down. No lagging issues at all, which is impressive for a wireless setup. The video quality is sharp, and the sound comes through crystal clear. We’ve only used it from laptop to TV, but the connection has always been stable. Highly recommend this if you're looking for a hassle-free wireless HDMI option.

Works great every time. Easy setup as well!

I believe this is exactly what I was hoping to get out of this product. It was a breeze hooking up and gave me the ability to use my DVR on my security system. The product needed to span over 100 feet so I would be able to see patrons enter and exit our indoor mini golf course.

Well packaged, well made. Not difficult to set up.Works well as a wireless connection between TV and Roku Soundbar SE as a streaming input to the TV.Does not work as a wireless connection for the Roku Soundbar SE to be the TVs soundbar speaker over the HDMI/Arc TVs port.It does not support the Arc function of the HDMI port.

The coax outlet for my cable TV service is on one side of my home office but my TV is across the room. I didn't want to run a cable along 3 walls so I bought this wireless transmitter instead. It's been working great for several weeks without any problems. Setup was quick and easy, just plug in the transmitter and receiver, and I'm very happy with the results.UPDATE: Well, it worked for 10 months but today I found there was no output from the receiver to TV. I have rebooted both transmitter and receiver several times, reconnected power and HDMI cables, changed the HDMI cable, re-paired the transmitter and receiver several times and tried a factory reset twice. I finally connected the receiver to TV using a VGA cable and that output worked but the streaming is lagged and choppy even though the transmitter is 18 inches from the receiver. The HDMI output is dead, and that option was the whole reason I bought this device. It's another bit of overpriced electronic equipment that has no warranty and fails after less than one year of use.

This product is easy to use and easy to set up. It is life changing for the office, it streamlines productivity. 10/10

Bought this for a 2560x1440 portable monitor, the 1080p mode works but if i set it to 4k mode I just get a black screen. Unfortunately it's not useable for my needs.
