The 670G

Hello! I'm a T1 for about 6 years now, and my parents want me to switch over to the 670G after using a t:slim for about, I would say, 5ish years. I agree with them because of all the features like, the CGM, and the meter communication, but I am nervous about switching. I don't know if it's because I just got the new X2 or it's because I am scared of what could go wrong. I also hear it brings down your A1C by half (according to the introduction paper we got in the mail) which kind of helps me considering I have a VERY high A1C. (9.1) If there are any Medtronic 670G users out there, I would love to know if it is a good pump or not. Thanks!
