If we can provide a sensor for your prescribed inhaler, we will supply it to you free of charge (shipping costs excluded), after receiving the sensor you purchased back, in an unused condition.
If we are unable to provide the Hailie™ sensor for your prescribed inhaler type, we will refund your remaining subscription after receiving the sensor back, in an unused condition.
