Patient Considerations
Active Lifestyle
Light on body. Pens are easy to use and do not remain attached to the body, sensor is waterproof.
Waterproof when submerged in 2.4 meters of water and must be within 20 (unobstructed) feet of the receiver or mobile device. This device is intended to help people with non-insulin requiring type 2 diabetes better understand their blood sugar numbers.
Avoiding Highs and Lows
Limited customizability. System integrates the Guardian Connect CGM for high or low alerts but requires manual dose adjustment and limits the ability to adjust insulin levels throughout the day.
Very limited alerts. This device does not provide alarms and alerts for high, low, and rise/fall rates. This device is intended to track and understand the effects of food on blood sugar for people with type 2 diabetes.
Comfort
Many components. Have to carry InPen and pen needles. CGM is attached to the body and requires more tape than other sensors.
Low profile and low maintenance sensor application.
Easy Insulin Dosing
Dosing recommendations. Displays dosing recommendations and reminders for long-acting insulin.
No options. Stelo is intended for use by people with type 2 diabetes who do not require insulin to manage their blood sugar levels.
Easy to Use
Simple design. Replaces regular insulin pen. No additional devices to add on.
Real-time data and alerts make dose adjustment easier.
Fewer Fingersticks
2 daily finger-sticks are needed to calibrate the sensor.
Factory-calibrated sensor. Finger sticks needed for backup only.
Privacy
Hideable. Pens are portable but visible when in use. Frequent injections are unavoidable. View recommendations and data on a smartphone.
Small sensor. Discreet and thin sensor that is easy to hide under clothing.
