Has anyone purchased and used these things for anY length of time?

I first heard of them in JJ Racaza’s course as a supplement to aid in deliberate practice for competition shooting. Max Michel has promoted it and Dr. Seth Haselhuhn (sports psychologist with GreyHive) says they are legit.
I’m skeptical and thought it would be difficult rigorously test it vs placebo effect.
But curious.
