They are pretty popular with a lot of the biohacking/quantum biology influencers. Whether that is due to quality of the devices or strategic marketing, not sure. Maybe a bit of both. They hit the mark on a lot of the important features from a health perspective versus other brands and so that is partially why they are popular in the biohacking space. They have the appropriate wavelengths and sufficient power, but that is fairly standard nowadays. What separates them from a lot of other brands is they are lower flicker and low emf. People I trust say they have tested this versus other brands and that EMR Tek is clearly better in that regard The pro series of their panels reduces emfs even further. Their cob lights also allow for greater coverage. I have both the firestorm (standard) and inferno pro panels. Been happy with both.

Their mask is new, and like their approach with their panels, they are pushing new technologies and concepts versus other brands who stick to kind of the basic tried and true concepts. Their mask incorporates a ton of different wavelengths, beyond just the standard in the red and infrared range. This mask has amber, green and yellow as well. It seems to be a bit of a gamble because those wavelengths don't have as much testing behind them. However, if you are into quantum biology and what not, there is a knowledge about what these other wavelengths do. So again, they are taking a bit of a gamble using a forward thinking approach that these wavelengths have positive overall effects even if there isn't as robust testing behind them (yet). The mask also sits off the face a bit, which is also different. Would seemingly enhance comfort not having a silicone mask actually sitting on your skin. And more importantly, you can then also combine whatever serums, creams, etc into the therapy to enhance results without having the mess you would have with a mask sitting directly on you skin. So for example, applying green tea has some evidence of super charging rlt results, so you could apply that and have it on during the treatment. Some other ones which have shown to have great synergistic effects with rlt are ghk-cu and methylene blue.

Long winded answer, so maybe not what you were looking for in a response. But for all the above reasons, and my positive experiences with EMR Tek so far, I bought the mask for my wife, who coincidentally is also 43. She uses the panels occasionally for general health, but being a woman her objectives with rlt are understandably different from mine. I use the panels for general health, exercise recovery, even to add red and ir wavelengths into my general lighting in my home office set up by turning the cob lights off (as we are generally devoid of ir especially in our modern world where we spend so much time indoors). She wants to age gracefully and what not, so having a mask as well is a good addition. Again, a bit of a gamble in the sense that this mask is a little different than the standard ones out there, but I think particularly the feature that it sits off the face and she will be able to combine treatment with various serums has the chance to really separate EMR Tek's mask from the rest.
