So far the app is incredibly glitchy. It glitched, ended a treatment after 1 minute and counted that as a full treatment. I called customer service who kept saying that I ended the treatment pre-maturely and accusing me of doing it when I was insisting that their app glitched. They could not fathom a glitch nor admit to it and kept saying “this was you.” It used an entire treatment. Customer service is literally pointless. This is the second time I’ve called them. The first was a glitch with their website where I couldn’t check out and the first person just got rude and said “yes it happens what do you want me to do about it?” I called again and the Second Lady realized it was a problem and escalated it to IT to have it rectified. I swear their customer service is garbage. Is the device worth all this? Doubtful. I’ve let others know to stay away in migraine forums. What a dumpster fire
