Connectivity issues every time I change a sensor, volume adjusting ear piercing alarms (when it randomly decides to go off. I've had many times where it doesn't alert me when high) and accuracy between the sensor and meter is always a 30+ point difference. Also, why don't you make it more compatible with android devices? They're just as popular and used as apple. 🙄 ready to ask my doctor for a different brand at this point.

My experience has been very mixed. I have had 4 sensors so far and half of them have been great, the other half have been terrible. Twice the adhesive wore off about halfway through the 14 day period. This most recent sensor continually gives me an "Alarm Unavailable" even though all permissions are given on my Pixel. The other two sensors I've used have been good. With the increase in price, I don't know if it's worth the hassle.
