I do. I'm not sure if you would like the whole text or just want to make me aware. I will try and upload what I have. The GammaCore has some favorable data and shows some promise especially in episodics. Still waiting for "real world" impressions. Many new technologies get initial enthusiastic thumbs up only to find subsequent use dampens the enthusiasm. The non invasive nature, portability and potential as a triptan substitute make it attractive. My biggest beef is the planned obsolescence of the unit. In the US it stops working 33 days after activation. For episodic use that is frustrating because you might buy one to have handy use it a few times and go out of cycle and 30 days later it is garbage.
