If you have both G6 and G7 supplies, you might be wondering which ones are worth more. Here's a direct comparison of current resale values and what drives the price difference.
G7 vs G6 — Current Resale Prices
| Item | StripValue Pays |
|---|---|
| Dexcom G7 Sensor (1-pack) | Up to $45 |
| Dexcom G6 Sensor (1-pack) | Up to $35 |
| Dexcom G7 Sensor (3-pack) | Up to $120 |
| Dexcom G6 Sensor (3-pack) | Up to $95 |
| Dexcom G6 Transmitter (new) | Up to $40 |
| Dexcom G7 Transmitter (integrated) | N/A — included in sensor |
Why G7 Pays More
- Newer technology — G7 is the current generation. More people are using it, so demand is higher.
- Smaller, all-in-one design — No separate transmitter to pair and replace. Simpler for users.
- Higher accuracy — G7 has better MARD (mean absolute relative difference) than G6.
- Direct-to-phone streaming — G7 doesn't need a receiver. More people can use it.
Will G6 Prices Keep Dropping?
Yes — gradually. As more people migrate to G7, G6 demand will decline. If you have G6 sensors, now is a better time to sell than waiting 6-12 months. The price gap between G6 and G7 will likely widen over time.
What About the G6 Transmitter?
The G6 requires a separate transmitter that needs to be replaced every 90 days. New, never-paired G6 transmitters still have strong value ($40 each). Once a transmitter has been paired, it has no resale value — it's personalized to the user's receiver or phone.
💡 Switching from G6 to G7? Sell both your remaining G6 sensors AND your spare transmitters. Together they can add up to significant cash.
