Duration and Storage
15 Days
Sensors last up to 15 days and need about 1 hour to warm up. They work between 50ºF – 113ºF and should be stored between 36ºF – 82ºF. They are usually shipped in 1–3 month supplies, which is about 2–6 sensors at a time.
15 Days
Sensors last 15 days. They are purchased over the counter. Works at 50ºF – 108ºF

Patient Considerations
Active Lifestyle
Long wear & water resistant. Longer wear reduces change burden; sensor design aims for robustness with movement. Water-resistant up to 3 feet (1 m) for 30 minutes (same standard as FreeStyle Libre family).
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
Continuous closed-loop insulin adjustment helps maintain tighter control.
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
Small & Discreet. Very small, discreet form factor, and minimal bulk.
Low profile and low maintenance sensor application.
Easy Insulin Dosing
MiniMed 780G closed-loop algorithm: adjusts basal and delivers automatic correction boluses using sensor data. Longer wear (15 days) means fewer interruptions in automated dosing. In manual mode, it still requires fingerstick confirmation before dosing from sensor values.
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
Longer sensor life and shorter warm-up (~1 hour) help with convenience.
Real-time data and alerts make dose adjustment easier.
Fewer Fingersticks
Factory-calibrated sensor. Finger sticks needed for backup only.

Privacy
Small & Customizable. Extremely small (about the size of two stacked pennies), designed to be less noticeable under clothing. Upper arm site only; discreet but still visible with sleeveless clothing. Alerts can be customized on the connected pump for quieter use.
Small sensor. Discreet and thin sensor that is easy to hide under clothing.
