I love that the device is small and easy to use. I also love that can be used along with other treatments, such as Nurtec or other medicine. Having used a TENS unit in the past for muscle soreness, I was accustomed to the sensation of the pulses. I find them rather soothing and feel better during the treatment. I wish the treatment was longer in duration, perhaps 60 minutes. I feel that I might find more complete relief from my migraines if the session was longer. Forty five minutes for some migraines seems to only take the edge off rather than eliminate it. Some sessions it has completely eliminated the migraine. I think that might be related to when in the day I get the migraine. The migraines I wake up with in the morning are usually the toughest ones to get rid of, and I find that taking other "rescue" meds is necessary. However if I feel the migraine coming on later in the day and can get the treatment started right away I have good success with getting rid of the migraine. Thank you for creating this device. Overall I do find it helpful in my ongoing fight with migraines.
