[0.3 lb] This small thing saved me time and energy while attempting to extend my video live capture... It works great and furnish auto-power to aliment itself when both ends of the HDMI in and out are connected. At first I was wondering how to pull an extended cord of outlet to charge it... and I found out it was not even needed! And Video streaming are clear and great! That little thing device is of great value and worth...�

But... I just purchased it, so will see how long will it last

[HDMI: 7-Channel] PURCHASED SEVERAL TO EXTEND. OVER 2 YEARS THEY STILL HOLD VERY GOOD

[0.3 lb] This does exactly what it’s supposed to do. I have a 4K Ben Q monitor and a 2015 MacBook Pro that I have running in another room because of fan noise in my studio. I have an optical thunderbolt cable but couldn’t get 4K 60hz at the tail end of my Thunderbolt Daisy chain. No cable would allow me to get 4K at 60hz at the distance I needed. The longest cable run I could do was 6ft or so and that was unreliable. I got a very short DP cable run directly into the repeater and then I ran a 25ft display port cable outside the room and tacked it to the wall. Works perfectly. Make sure you have the shortest possible cable running directly to this box from the source. This is a great solution and doesn’t require you to spend $350+ on optical cabling that dies after a couple years because the lasers and sensors overheat.

[HDMI: 7-Channel] Was having issues with my signal dropping in and out. I could not display 1080 at all until I installed this device. Now I get 1080P signal to the TV in the garage. It is roughly 125 ft.from the cable HDMI splitter and works great.

[HDMI: 7-Channel] A while back I bought a KVM for my various systems and several Raspberry PIs. The HDMI didn't work for the PIs. I thought it was a problem with the KVM. I saw online that someone suggested boosting the HDMI signal, so I bought this. I plugged it in between the monitor and KVM and it did the trick. All my PIs now have HDMI. I didn't need the 5v power supply.

[0.3 lb] I am using a 50ft HDMI extension: source-50ft cord-booster-8ft cord. At first no signal would come though. When I added the booster, the signal worked but would drop intermittently. So I added the power adapter and everything works fine.

[0.3 lb] This product does what is it supposed to do.  But that is not the most important factor of my review.  When our state’s governor said our Mennonite community could not meet in our sanctuary because of the exponential increase in COVID-19, I was asked to put together live streaming for our worship the next Sunday.  Of course our church had never done anything similar and my previous experience
was hooking up a home DVD player.  I needed to order a number of items, get them shipped and received, and set them up in the sanctuary before Sunday. 

In the midst of a pandemic in NYC and NJ I knew B&H would do their best to get the items shipped. We made the Sunday deadline and the response from the community was gratifying.

Thanks, B&H.

[HDMI: 7-Channel] This little inexpensive HDMI amplifier block was inserted into a line from a consumer camera going to the video switcher in our church. The specs said that the input side should not exceed 80-feet or so. We knew we had exceeded that by about 10-feet and had been warned that the output signal from a consumer-grade camera was not as robust as that from a Blu-Ray player or cable box. There was fear that this unit would not clean up the red sparkles in the picture on black objects we suffered from. But when the booster was inserted in place of a cable coupler close to the switcher input selector the picture jumped to correct color rendering. We are completely satisfied with the product and probably will order another to hold for future use. It performs better than the advertised specs in a tough situation.

[HDMI: 7-Channel] Been having this for 3 years non stop, and been working GREAT. Never had to even use the DC connector , cause both Hdmi bring in enough power to power on the device and boost connectivity. Video output crystal clear.

I think today Bought 4 or 5 units.
Will definitely recommend

[0.3 lb] Not much to say other than it does what it says, and was easy to put in place.
