Características:

It is great for it's size and the picture is clean. I sense the sound is lower than normal. It's definitely different than when I have it hooked up to a vcr. Another important part to mention is you can only run one RF signal through it. If you have an RF splitter and running one signal for the composite, then the other part of the splitter can not run say a RF only console. It is not good for RF only consoles and is a downside for me. A switching capability from IN LINE to ANT like VCRs and RF modulators is definitely a missing feature for this device. In conclusion, it is strictly great for RF only TVs but not for RF only consoles.

*Update*
I had opened the Reflex up and added a switch to the device to allow switching between LINE and ANT. I have added an extra photo showing the extra switch next to the 3/4 and RF line, and video to show it switch between signals. There was plenty of room inside the case to add it and was very simple. I have changed my review from 3 to 4 stars. I want to add the extra star because I like how well designed the product is to allow me to add the extra switch.

Very pleased with the results. The picture now looks as cheap as composite and brighter too.

This purchase came about because unfortunately I had to part ways with a late 00s TV with all the bells and whistles due to being too large and heavy and downgraded to a 90s consumer CRT with only RF. My old adapter from the early 00s was never that great and I wasn't even sure if a new one would even be an improvement. However when I first hooked it up and channel 4 was a solid black with no fuzziness, I was more than satisfied with my purchase. Works perfectly for 15KHz sources and looks just like I remember. Turned an RF-only TV into a 95% of the way to a composite TV overnight.

Hooked this with a Nintendo and tried it on a couple of old CRT televisions from the mid-80s and found it superior to my old RF adapter. Also in a niche case hooked it up to a Vega 9000 supergun and it handled that no issuses whatsoever. Nice piece of kit!

I recently received a 1984 19" Zenith from my uncle. It's one of those older models with the VHF and UHF knobs and the antenna screws on the back. I needed an RF modulator, but the ones I had in an old drawer were disappointing.
That's when I found the Reflex RF. With a set of high quality composite cables and the included coaxial cable this tiny Adapter produces a picture that could easily pass as native composite. The Reflex RF adapter just made a very old TV into one of my favorite CRTs for gaming.
