Sell Dexcom G7 15-Day sensors for cash

Dexcom released the G7 15-Day sensor in late 2024, and it's rapidly becoming the most common Dexcom product we see from sellers. Many patients who switched immediately were left with boxes of original G7 10-Day sensors they can no longer use. If you have either G7 version, here's how to tell them apart and what they're worth.

G7 vs G7 15-Day — how to tell them apart

• Check the box logo. The 15-Day version says "G7 15 Day" in the product name. The original just says "G7" with no "15 Day."
• Warm-up countdown. G7 15-Day shows 60 minutes. Original G7 shows 30 minutes.
• Wear time. 15-Day lasts 15 days + 12-hour grace. Original lasts 10 days + 12-hour grace.

Why the G7 15-Day commands higher prices

1. Current flagship. As Dexcom phases out the 10-Day G7, demand shifts to 15-Day inventory.
2. Lower monthly volume needed. 2 sensors per month vs 3 — each box is more efficient.
3. Improved accuracy. 8.0% MARD vs 8.2% for the 10-Day.

Why people have surplus G7 15-Day sensors

• Switched from G7 10-Day to 15-Day mid-supply-cycle and have leftover 10-Day boxes
• Switched from G7 15-Day to FreeStyle Libre or OmniPod system
• Insurance formulary change requiring a different CGM brand
• 90-day auto-shipment before a prescription change
• Estate situation — family member passed with supplies remaining
