At a buck sixty to three bucks a pop depending on the model you buy (Obamacare tax not included)... I'm not sure it's worth the effort or cost...
Oxygen therapy at the higher inhalation flow rates that support hyperventilation (25-45 liters/minute), is far more effective in achieving a complete abort, a lot faster and at a lower cost/abort when using the larger medical oxygen cylinders M,H,K,or welder's O2 equivalent...
I tried electrified acupuncture at NIH with needle placement all over my head and neck to the point were I was twitching like a big dog leaning on an electric fence... no joy... In three separate attempts... the CH steamed on at full power for the full 1.5 hour duration on all but the third attempt...
I had two staff neurologists there for this attempt because they were uncomfortable with the volume of oxygen I was going through each month... Neither had ever witnessed a patient presenting with a full blown cluster headache...
One neurologist couldn't take it and left the room after less than five minutes watching me writhe in agony... The second finally relented a few minutes later and let me start oxygen therapy from a wall mounted flow type regulator in the exam room.
He was surprised at the flow rate I was using... He kept taking my pulse and checking my eyes... I'm sure he thought I'd pass out from the high oxygen flow rate... I didn't...
Ten minutes later I'd aborted the cluster headache...
The neurologist just stood there shaking his head in disbelief... His only comments were "I had no idea how painful cluster headache attacks can be..." and "I'm still uncomfortable with the oxygen flow rate you're using... but I can't argue with its effectiveness..."
If nothing else, this contraption might just keep the user busy enough during hits to think it's really working...
In short, without the results of a level A RCT on the efficacy and safety of this device for migraineurs and CH'ers from a respected University Hospital or major headache institution... I'm skeptic at best...
See the following link for the animal studies on this device and one brief test of an implanted vagus nerve stimulator on four patients with epilepsy they claim this device will emulate:
