Love the patches for G7. I use the ones that say “type 1 diabetic”. I don’t like wearing a medical alert necklace or bracelet, so I use the patches as one! Just in case of a car accident or medical emergency where I am not with a loved on that knows my condition! Plus, you cannot even feel them and they add an extra layer of protection. My G7 is supposed to last for 10 days. Before using these, inevitably I would bump my arm or something and the sensor would come off. Now I am able to have it last for 10 days!
