Review: Nice - Seems to work flawlessly. I appreciate that the main unit supplies POE so not need for wall power at TV. It’s one less thing to deal with.
Review: Solid Signal - Been using it for a month now to connect a projector to a home theatre system. Zero drops/glitches/handshake failures, very good. Delivers a full 4KHDR signal. The only "con" is that some devices don't seem to think the 4K signal is possible and you have to manually set it. Like on first connect the Roku defaulted to 1080i and I had to set it to 4K in the settings. Now this could be my AVR or something else, but it's just something to keep an eye on.

### ⭐⭐⭐⭐⭐ Excellent Technical Support and Clear Picture
*by M***7 on January 26, 2021*

So I read all the reviews on this product and ones just like it. But from all my research it seemed J-Tech was one of the best so I purchased the extender. Seemed simple enough. Plugged everything in, and nothing. No picture. So I spent a day troubleshooting myself. I made sure all the components worked on their own when not connected to the extender. So had to be the extender right? So I sent a lengthy email to J-Tech. The next morning Nathon G. from tech support responded and asked me to try a different troubleshooting technique to make sure the extender was working, which I was able to confirm it was. The next day he sent me information from my monitor manual and recommended I reduce the refresh rate on the NVR. Wouldn't you know it? Boom working like a charm. Excellent response time and a very thorough review of the other components in my system, that were actually causing the problem. I will definitely purchase J-Tech in the future as well as recommending their products.
