Zero stars. The device does not connect with the app, making the device unusable. Would not recommend this to anyone!!

Havent received the product, no updates or tracking or order. Support not answering.

Worthless

It is not helping with my migraines. The literature that comes with a device is very vague and not helpful. The counselor I spoke with on the phone was very helpful.

I had to stop using it because I was getting more headaches
