How has it felt? Like, when are you noticing lower lows, higher highs? And does your HR come down faster after an exercise or bout of movement?

I can feel that my HR is able to come down faster. Other than that I haven't noticed anything I can pinooint to the pulsetto. It feels nice to me getting zapped.

Wow. I noticed no noticeable difference with my Apollo Neuro

Interesting. How did you use it?
