Limited customizability. System integrates the Dexcom G6/G7 CGM for high or low alerts but requires manual dose adjustment and limits the ability to adjust insulin levels throughout the day.
Comfort
Low profile sensor and small adhesive.
Many components. Have to carry pens and pen needles. CGM is attached to the body.
Easy Insulin Dosing
Scanned sensor trends can be used for dose adjustment.
Dosing recommendations. Displays personalized mealtime dosing recommendations.
