I would love to have a reliable device for at home Neurofeedback training bit I find these products quite questionable, especially of they have dry electrodes, also they require correct usage as muscle contractions can easily kill you readings. Researching which ones are BS and which ones might be usable is also quite difficult as I have not found a reviewer who is knowledgeable in the subject, if you know one please comment, I‘d love to figure this out.
