Hi
@Helpme . There are a few folks that have reported some suggestive experiences with the HDR and other devices discussed here. The vast majority of people on this forum, though, see these devices as objects of debate, ridicule, speculation and, for some of us, experimentation. Not to speak for others, but my impression is that even those who have had personal experiences they would consider successful would not suggest that someone can just purchase one of these devices and expect it to work for them out of the box - these devices remain experimental works-in-progress and if they have any effect at all it appears to be very dependent on subjective factors (mind set, personal previous experience, and perhaps other unknown elements). In addition, I have not seen any anecdote of a "successful" experiment that has demonstrated the type of control of results that you are looking for. Finally, please exercise caution. Your request for help strikes me as a bright beacon for con men, rip-off artists and shady operators. Take care!
