This is far too much information for one video, yet Ive gone ahead and done it anyway. I will slowly break it apart into separate subjects, but for now, here is the comprehensive summary!

In the above video I go over the hardware of the Dexcom G4 sensor system. I show how to apply the sensor, the iOS Share application, the Apple Watch application, and finally compare it to the Medtronic 2nd Generation Enlight Sensor.

Ive tried out both systems for extensive amounts of time and there are pros and cons to each. As far as just the Dexcom system is concerned... here is the pros and cons!

  • No need to charge
  • Share functionality

  • 2 sets at once
  • No alerts on phone/watch
