I agree with what you said Sageous, and I also tried to avoid the "AMAZING, 100% WORK" appearance. it's like the author works this way, he is also the creator of the soon Instadreamer revolutionary incoming new stuff blablabla
So, like I said I tried to see beyond this SCAM appearance and to see what is this technique, what is new in it.

First, I don't see where you and VagalTone see this as a WILD technique.
It's not.

Basically it's rather a DILD technique starting from a first Alarm that is supposed to wake you up.
Then you stop it and another sound, totally different and not supposed to wake you up, is programmed to go off few minute later.
In the mean time, all you have to do is to return to sleep with the idea that you're gonna fall back to sleep very fast , thus that you're gonna dream (hopefully) , and you must tell to yourself that if you hear this sound, you're dreaming.
This is closer to a MILD technique but assisted with an external audio.

The new stuff, what I found interesting, but like I said I have no Idea if it actually works, is the idea that once you are lucid by hearing the sound, if you move away from its source in the dream the sound will disappear.

I wish I had a LD on my trials (but only tried a couple of time) to check this idea.
If this technique works, (to have lucid dreams) I don't see a need of doing all the extra work other DILD techniques are based on (RC, DJ, WBTB, etc..) but it does probably need a certain amount of prospective memory. not so much since you are supposed to fall back to sleep very fast.
