Show me their wearable device, that fits on your wrist and sends a continuous EKG, heart rate, sat levels, etc.. Send me a pic of there wearable device that does that and I will shut up. But I just studied there website and they don’t have one. Have you ever had to wear a holter monitor for several days? Thousands of people have to wear those, then they have to go in and have the data read, this simple watch will do away with those!
