Patient Considerations
Active Lifestyle
Waterproof when submerged in 2.4 meters of water and must be within 20 (unobstructed) feet of the receiver or mobile device.
Limited Adjustability. No way to adjust long-acting insulin for higher activity on the fly.
Avoiding Highs and Lows
Custom alerts can be set for highs, lows, and rapidly rising or falling glucose levels. Trend arrows show the direction glucose is heading, with the rate of change.
Limited customizability. Requires a high level of engagement and effort to avoid highs and lows but can be paired with a CGM for improved blood sugar control.
Comfort
Low profile and low maintenance sensor application.
Many components. Must carry insulin vials and large syringes but nothing attached to the body.
Easy Insulin Dosing
Real-time data and alerts make dose adjustment easier.
Requires attention. You have to do the math to figure out your dose. Unable to adjust basal in real-time.
Easy to Use
No scanning required. Readings are sent directly to the mobile app every 5 minutes.
Many steps. Requires effort to figure out doses and deliver insulin every single time you need it.
Fewer Fingersticks
Factory-calibrated sensor. Finger sticks needed for backup only.
Frequent finger-sticks are required.
Privacy
Quiet Mode (Vibrate). All system alerts will vibrate when this setting is enabled. Urgent Low Soon and technical alerts will sound if not acknowledged.
Hideable. Vials and syringes can be hidden when not in use but very visible when in use. Frequent injections are unavoidable.
