I purchased a professional/unlimited NO system in December 2021 to use on myself and family. I now have access to another neurofeedback system and am willing to part with the NO. Everything works perfectly and I will have it serviced (by NO) before I sell it. Asking for $7000 plus the transfer fee. I am from the US. Please reach out with any questions 
Is it still available, and where are you located in the US? Best wishes, KD
Yes it is still available and Iām located in Hawaii.
