The app is so awful that it negates any benefits the device might confer. Such a missed opportunity.

The electrodes tend to fall off as the cephaly device is too heavy for the electrode. Perhaps a headband might help the electrode stay in place versus having the middle pull away or the sides pull away, etc.

I returned it a while ago, so it definitely did not work for me, but made it worse

frequent replacement with newer electrodes

I tried to contact you to return the device and get a refund, but you never replied.
