To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
The device works, and in certain cases it'll be good. However, there are some things you need to know:
- 50 feet/15m is probably perfect line of site. I can get it to work at 30ft, but the antenna has to be adjusted just perfectly.
- IR blaster is inconsistent at best.
- Screen resolution is correct, but the bandwidth makes for a blurry screen. I expected this; it's doing a superfast reencode and sending it over its own wifi quickly - no way it'll be pristine. This is fine for me, but be aware it looks a bit "standard def". I know that's a technical limitation.
I would be ok with it if the remote blaster worked better. It's just not that great. It has worked in some use cases that I needed that aren't normal, but now that you know what some of these limitations are, you understand what you're getting into.
Would not hold a connection for more than 5 seconds at only 10 feet. J-Tech Digital charged a restocking fee. After contacting them they insisted the item was not defective and would not refund the restocking fee. I would not recommend this product. Update: J-Tech refunded the restocking fee after I contacted them again and reiterated that the product did not work.
It works great. We keep it about 15 feet away from our security box and it sends the signal nice an clear. Sometimes it will cut out but I believe its because we don't use the usb base plug to keep the sending receiver on, I keep it plugged in the security box for power to it. Still works nice. Would be nice if it came with a 6 or 8 inch hdmi plug to hide it behind a monitor, just for suggestion.
Range is abysmal. It regularly loses signal within just a few feet... there's no way it would ever achieve anything remotely close to the advertised range. Not worth the trouble. I wish it was better, because I really wanted to like it - the size/etc is convenient, but if I can't rely on it it's unacceptable. Returned.
Well, it is great for what it advertises. The "wireless" reach is nice, however there's no audio transmission over HDMI, the case of the HDMI transmitter transceiver goes about 1/3" too wide so that it covers the USB port on my laptops to use it on. Likewise, the audio transmitter has to wrap around the back of my laptop to plug in.
Form factor troubles aside, this lets me use a projector with my laptop — without many cables at all!

This is my third J-Tech Digital Wireless HDMI device. The other two have transmitters and receivers with antennas, and they work perfectly for transmitting an HDMI signal wirelessly. I use the other two with cameras and have no complaints about the qaulity of the picture or the distance over which the signal can be transmitted (I use them to send an HDMI signal approximately 50'). This device differs from the other two because the transmitter is a simple dongle that plugs into the device you want to transmit from, rather than a larger box with an antenna. I use it to send an HDMI signal from my laptop, which sits at a workstation to my television which hangs on a wall about 35 feet away (without this device, I would have to unplug my laptop from the docking station, move it near the television and connect an HDMI cable between the laptop and the television). The dongle requires power, however, the laptop itself can provide the power, if you plug the USB end of the power cable into a USB port on your laptop (assuming you are using the device to transmit HDMI from a laptop). The device works flawlessly, but there are two things you should know. First, as the description says, this is a line of sight device. In other words, the HDMI signal cannot be sent through walls. Second, there is a slight delay in the transmitted signal. For instance, if you were to watch video on your laptop while projecting to a television, there would be a slight lag between what you see and hear on your laptop and what is projected to the television. It's hard to think of an application where this would be an issue, but it's something to keep in mind. While running an HDMI cable from a device to a monitor/tv is definitely a cheaper option, there are applications where this isn't practical or desirable and the J-Tech transmitter/receivers are ideal in such situations. It's a bit on the expensive side, but the quality of the equipment is excellent.
I've had the opportunity to try several products from this brand. This one is my favorite. I like it because I don't feel tangled in wires when using it. It's truly plug and play. You can use it with devices in the same room. The quality is excellent. You also get lifetime customer support. I think that's a major advantage and a reason to choose this brand over others. For that reason, I highly recommend this product.
Thanks so much for taking the time to read this review. I hope the information that I've provided helps make your decision a little easier.
