  • Works for old CRTs
Worked for me to run a dvd player into a small old CRT tv where the composite was broken. Ran this into the coaxial in the back of tv for the dvd player

  • Easy to use and works right away.
The media could not be loaded. This modulator was well packed and came with everything pictured in the listing. I used it for playing DVDs on my analog T.V. which worked instantly. While there was no instruction book included, it was easy to figure out. It converts audio and video signal very well.

  • Easy to use and worked great!
The media could not be loaded. This worked great for me. I bought a 1981 console tv and wanted to hook up a vcr for a vintage vibe. Easy to hook up without directions. Very intuitive. I did need a coaxel adapter to get it done but that was super easy. Both sides were female and the coaxel for this is felmale so I needed a double female adapter. If I had realized, I would have ordered that when I ordered this, but it still wasn’t a biggie. ... show more

  • It works.
Used it to run a second TV from the main box. It worked well but it is not as clear as the main TV.

  • Dead Stick - Doesn't Work and Doesn't tell you even that
Dead Stick is like a rudderless/engineless ship at see. That was my experience. I followed logic (as there are no instructions) and hooked it up. Nothing. I then crawled under my house to see if there was a cable issue. Nothing. I moved it to another TV. Nothing. Finally, it dawned on me that maybe it wasn't getting power. Sure enough, the power supply was fried...no power at all. So, i reached into my bag of tricks and found a transformer with he correct voltage and connect, and tested it to make that it worked. Great. I plugged it in, and ....Nothing. I'm fairly certain i lugged it in correctly (I followed the picture and referred to instructions provided for other manufacturer's model). The unit has no lights, so i don't know if the until is as fried as the transformer or why it doesn't work. I'm just Dead Stick. Fortunately, necessity being the mother of invention, I realized that an old VCR or DVD player (or in my case, admittedly, my current VCR), can be used by hooking up the VCR to receive the RCA inputs from the TV and then hoking the COAX between location A and TV-B to the OUT connection on the VCR. Plug the other end of the Coax into TV-B's IN connector, turn to channel 3, and you're all good. Just don't let it get around that I still have a VCR. The VCR is bigger and uses more power, but it works, and is just collecting dust or filling a landfill otherwise, so give it a shot and save yourself some headache. ... show more

  • perfect for the price range
This thing kicks ass, I didn't think it would be remotely decent for how cheap it is, but I was pleasantly surprised. Came in handy when the only working crt I still have isn't modern enough to have its own rca ports. I honestly can't tell that much of a difference in quality compared to if it was just running straight through without any adapters. 10/10, reliving childhood perfectly. Never thought I'd be able to enjoy my old consoles and tapes again without it looking like some genre of garbage. if it looks bad or wrong, its nothing that cant be fixed by adjusting the color/picture balance on your tv. It took about a half hour of tweaking for me, but the tv i had was at weird settings to begin with anyway. Some other reviews said there was interference issues but I've had no such thing yet since buying and I've been using the thing every day now with no issue. There might be more expensive, "better" hardware out there for this but I don't think it would be that noticeably better or different. (phone/lighting quality sucks I promise it looks FAR better in person) ... show more

  • Works exactly as advertised.
Works great. Wish it would have come with a coax cable as well but no biggie.

  • Works with Roku
Works well. Was able to connect an old Roku LT 2700X to it and then using an antenna cable to the 5” CRT TV I had. Able to watch Roku live channels on the TV now. In the photo you can see NYC Mayor Elect Zohran Mamdani giving a speech.
