Yep,
I read your post to fast and missed the Ninja link. From what I can tell there was also a failing out between Ninja and Guga..
Yea the stuff they come up with is really good. What I really like is that they do side by side testing. So instead of just trying a something like a marinade one one steak, they use four different marinades and then no marinade. Many of the things have done have saved me tons of time, since I can see the results that they have done.
Anyways, if you are into Sous Vide, check out the channel.
