I love the Cefaly!!!
My brother brought me the Cefaly from Canada last year, so I have the one with 3 settings. I usually get migraines 1-2 times a month, and I've been using the Cefaly when I feel one come on. So while I haven't used it daily, I can attest to how well it has worked in stopping a migraine from going full-blown.
To me, the Cefaly is not uncomfortable. I actually like the feeling, it's like a scalp massage and I often doze off when using it. But from what I understand, people react to and tolerate the Cefaly differently. A friend of mine finds it unbearable.
Reading through other user's comments, I think I might start using it daily to see if that stops my migraines altogether. Any tips on extending the life of the electrodes?
