Dexcom Stelo
The most flexible way to try a CGM in the US without involving a doctor. If you take insulin, you want a sensor with alarms instead — this one has none.
Sibionics GS1
The most interesting budget option: it costs well under the mainstream sensors and, unusually for a sensor you can buy without a prescription, it has alarms. The trade-off is that you are trusting the manufacturer’s own accuracy figure rather than an independent one.
