Earlier this year, Dexcom offered a 20 day free trial which I took up.
I think I am the exception
- I found the Dexcom app very basic.
- I found the sensor plus transmitter combo bulky
- I disliked the excessive non recyclable plastic in the applicator
- i found the readings to be inaccurate. They were not consistently out in one direction but rather noisily variable and did not stabilise over the life of the sensor. As the trial was two sensors, I assumed the problem was me rather than the sensors.
I decided to save my money and stick with my Libre 2 / xDrip combo which I calibrate twice a day. The calibration frequency is more peace of mind as it is rarely out more than 10%. I am happy to use this for insulin dose calculation.
