J-Tech Digital Wireless HDMI Transmitter and Receiver 4K 60Hz Up to 196ft., 5.1/5.2 GHz Low Latency HDMI Loop Output SSID Pairing Channel Change IR Passthrough [JTECH-WEX4K-50]

I bought this for my office so that I could duplicate one of my monitors from my PC so it's easier to hold a meeting on a conference table in my room without turning my monitors. My company distributes AV video equipment so I've tried many products from logitech & the like but this has been the best so far.Whats most impressive is the wireless transmitter is under my desk & I've never, ONCE, had an issue with it syncing, video or sound quality, etc. Also the receiver is connected to a monitor on a mobile cart which I have to unplug from time to time when I'm moving it & I've still never had an issue with syncing, video or sound. The receiver is very easy to mount as you can see in the photo and is very light and compact. The antenna is large enough as well & is easily adjustable.You need the HDMI extender which is only a few inches long so you might need to purchase a longer extender if you want to avoid clutter near your devices since the transmitter is the HDMI output. Also the transmitter is a little heavy to hang from anything horizontally so the extender is a must unless you can mount it vertically like I do in the photo.

We use this in our Church for the monitors showing songs and scriptures. Does exactly what we wanted.

The device keeps dropping the connection. It is also getting more difficult to get them to pair again. Most times we get the audio but not the picture!

I bought this product for my conference room at work because there is low lag and it's easy to use for both macs and pcs. All you have to do it plug in the HDMI, UBS and the signal shows right up. The unit worked flawlessly for just over a year when we ran into a problem with the dongle. I contacted J-Tech, they looked my order up and replaced my part within a week. Great customer service!

I helped set this up for a friend of mine who wanted to put her TV where there was not access to a hardwired cable hookup. It's only about 15 feet across the room from antenna to antenna. It works well.Unfortunately, soon after the install it stopped working. I got on the phone with a service tech and had them help me run the system through some checks. It turns out the package was already defective, 5 months on. We asked for a refund, and they would not do that. They offered to send us a replacement. That is now in place, and so far works fine. But, personally, I'm leery of it's durability over time, hence the three star review.

This works great in a SINGLE location; however, we have multiple conference rooms and they are not designed to work individually. Each device attached to the first one set-up. There was no way to change the channels. SO, we kept one for our main conference room and returned all the others so we could get dedicated extenders for those. Works great in the one location.

I was skeptical (remembering when "plug and play" was an unfulfilled promise), but we unboxed this thing at a big event, plugged it into a projector on one end of a large room and a laptop on the other, and it just worked. We didn't even need the "extra power" USB cable. It was like having a cable connection.Haven't tried the audio yet; if there are problems I'll update this review.

I rarely write negative reviews, but I think I got pretty burned on this one. I purchased this as a wireless solution on set for film production. The best I can say is that it worked, sometimes. If there's literally ANYTHING in the way of the receiver, it loses signal. If you go more than about 50 feet away, (I got the one rated for 164ft) it loses signal. If it loses signal, most of the time, you have to power cycle the receiver, transmitter, or both for it to reconnect.When it worked, it worked REALLY well, transmitting both video and sound pretty flawlessly. But it just wasn't reliable at all, and after just three projects, the USB power plug is loose, and does not keep a power connection reliably any longer.This product might work well for stationary uses, but putting it on a shoulder rig, and moving around with it, it's junk. Frustrating and a waste of my $200. I'll be biting the bullet and buying a Cinegears Ghose-Eye system. And that's a shame, because it CAN work.... it just doesn't.
