The device seems to be designed for Neurofeedback, and it can measure frequencies relatively accurately. It has two built-in feedback measures "attention" (mindfulness meditation) and "meditation" (more like loving kindness meditation). The raw signal can be used to develop your own classifiers/feedback measures.

Currently I think the practicality of one dry sensor on a wireless headset, combined with the cheap price, beats every competitor on the consumer level.
