Yes, I did, and it didn't work for me. But, try it.

I love my Cefaly device but I do know that some people don't like it.
For me it's like a massage inside my brain.
I have had constant migraine since January 2008 so it doesn't get rid of mine but it is a wonderful 15 minutes and lowers my pain for a while longer.
My neurologist gave me a prescription and they gave me a discount because of that. Still I paid $250 but for me it is worth it.
Any bit of relief is awesome.

Doesn’t work. Don’t waste your money!
