I've heard that there are good domestic CGM blood glucose monitoring products, are they reliable?

I feel fine, according to research, CGM is one of the best outpatient glucose management methods for lowering glycated hemoglobin.CGM has become the "gold standard" for glucose management. With active monitoring and alerts, CGM is especially suited to children (and even older adults) with nocturnal fluctuations in blood glucose, providing safer care and greater peace of mind for caregivers, so it's safe to use for your family!
