Not only amazing, but in our hectic world I believe this headband to be essential. I bought it for seeing the brainwaves and that alone makes it a must buy at least once in your life. What I have found amazingly is the tracking of your stress level. I work in IT so knowing exactly how stressed I am informs me when I am more stressed than I realize.

A couple years later I found the Flowtime Biosensing headband and have since done several hundred sessions with it. It's reliable and accurate over the years. I'm happy to see that all the data, including brainwaves, heart rate, HRV, coherence, attention and relaxation. I find these additional metrics very useful to see the fuller picture of how meditation affects body and mind.

Best device that monitors your brain and heart coherency. I love this device I researched all the other brain wave devices and none of them can do all of this. If you want to know what state and how well you are developing in your mediation practices then this is for you. It is a great price for all that it accomplishes and great tech support.
