Mine the Rivieo came with an arm band that was too long to wrap around my arm and secure the device tightly. I woke up with a migraine and put it off trying the new reveal because I had been told that new reveal was sending me a shorter or a band And wanted to wait until then. The migraine can I help control and say used as a face for a session while holding it on my arm, but one side of the electrode pads slid away and out of position. I have contacted Nerivio Customer Service and sent photos of the device as it looks now as requested. I am waiting to hear back. The device did not help my migraine; whether that is because I waited too long to try it or because I did not have a proper arm band that fit, I do not know. Nerivio should ask when ordering what size arm you have. If I had known the arm band would be so long I would have told them that my arm is the width of anadolescenct’s
