CEFALY Connected

The device works great, but the shipping box was torn open and the product has no other seal. So i don’t really know if it’s been used before and that’s pretty poor for a medical device that I need badly. I hope that if there is any issues with it i could get a replacement. But honestly need the device too badly to send it back wait another week and i can’t necessarily afford a second one. So far it does a good job other than sometimes it feels like only one side working before both sides turn on higher levels

Just started recently so can’t say much

The product itself is wonderful. But I can’t get more than 2 ft away from it before it becomes disconnected. I have blue tooth headphones that stay connected even if I leave it upstairs and go to the basement
