It's been a while, but he states that they did extensive research of other attenuators and that Rivera is the first to offer variable ohms. Which is BS. Hot Plate, Phantom. I'm sure others. There were a few other things. Claiming how bad others were made and how much better theirs was. The Faustine is built like a tank. So is the Hot Plate.
It may be great, but when he is giving false info and spends so much time putting others down it just is a red flag to me.
