It seems a bit rich to me having a company with $30+ billion in sales every year asking their customers to fund their gamble. Is there even any data on if this works or not? I couldn't find it. Let me know when there's a product I can test and review.
@swyfe Plus, it only ships to US!
This looks remarkably similar to FOCI or Spire. Is there only one form factor for these devices?
