The Peak BrainHappiness Home Training System is a refined and simplified version of the professionally-oriented Peak BrainHappiness Trainer with fewer designs and without the Alertness biofeedback. It enhances your ability to focus and a wide variety of positive feelings. It arrives with a Windows 10 laptop, fully installed and ready to use, including a (hard to find) DVD player. Purchasers outside North America may receive a different headband with 50 Hz. electric current filters.
