I finally finished watching the biofeedback training videos that were recorded on May 2024. It was their newest versions of the demonstration and instruction videos. When I watched all of their instruction videos before I received the device, it was too quick for me to understand. Now I have my device with me and used it more than 10 sessions, I finally start understanding about their panels and commands gradually. The two instructors have been using this device about 20 years. I have many more years to keep using this device and understand it more clearly. It is fun to learn new things.
