My only complaint is that the device only has 12 treatments. As someone with chronic intractable migraines with 25 to 30 migraine days a month this is going to end up being pretty costly for me. Why not charge a higher amount for a device that can be charged and used over and over. I realize and have read that you have a recycling program, but still it seems like a huge waste of resources. I understand that you have a significant upfront cost with the design,development, and research for the product, however I think you are engaging in a little bit of nickel and diming.
