I have been a board-certified Neurofeedback practitioner for many, many years and have tried most headbands on the market. This one is beautifully made, charges quickly, connects to Bluetooth almost immediately which is a huge improvement over other devices, includes enough programs and exercises in the app to keep you busy but not so many to overwhelm you! The tech-support is impeccable and the price point is extremely reasonable for the product that you are receiving. I have a lifetime subscription and I am recommending it to all colleagues, clients, friends and family. I highly recommend this device to anyone who wishes to train their brain non-invasively for peak performance and calm focus. FocusCalm wins!
