Avoiding Highs and Lows

Alerts are not available. High or low glucose alarms are not available. Trend arrows show the direction glucose is heading, with the rate of change. 

Easy to Use

Requires scanning. Self-application and manual scanning every 8-hours are required. Easy self-application.

Easy Insulin Dosing

Scanned sensor readings can be used for dose adjustment.

Fewer Fingersticks

Somewhat discreet. Scanning feature makes it easy to monitor blood glucose levels discreetly.
