Just received it yesterday. Not sure about it yet. Set up was easy. First treatment didn’t do too much, but turn again, headache came in overnight, so it had surest been over “60 minutes..” I have some feedback, though, on the accompanying relaxation video. The graphic of the “treatment working on your brain” is a bit distracting since the diagram is not anatomically accurate. The spinning brain shows what looks like a frontal lobe and parietal lobe, but lacks the occipital lobe and cerebellum, (the hook part on the back of your skull.) Since this is where I get all of my headaches, it was hard for me to buy into “the treatment is working now” as I watched a graphic that completely discounted the parts of the brain where 3/4 of my migraines originate. Maybe in the next software update, make the graphic a bit more convincing so it recognizes that feeling in the back and top of the head is transmitted by the two greater occipital nerves. Ok. Now, I’m on day two and I tried it again. Today I had some connection difficulties. I had to manually connect the Bluetooth and the device disconnected twice before the session could start. Finally, I was able to get it started. I didn’t see much relief from my migraine, but perhaps I have a different sort of migraine than this device is targeting. The app is easy to use.
