It's another thing attached to you. I don't have a problem with this as my CGM has helped me a lot. There is only one pump and CGM that are linked. I do not use that brand. So I have another device to carry. Again, I do not mind this. I've been able to get back in the gym and in general have been able to have a lot more freedom since getting on the pump and adding a CGM to my maintenance. I've been a diabetic for over 31 years.
