My endo continues to encourage me to leave my Dexcom G7 behind and try out the newest version of the Medtronic cgm closed loop system. I had heard that the Medtronic cgm was awful. Has anyone tried this yet? I really need to hear some feedback.

Hi @daisymae ! It’s been a while, I hope things are going well for you. I have not tried the Medtronic although I spoke with an acquaintance a few months ago who reported it as “fantastic” but has never used anything else but Medtronic so might not be a reliable source. The tubes are a non starter for me, whatever I do has to be tubeless. I personally am sticking with Dexcom and Omnipod for the foreseeable future.

Have you tested out the libre 3 plus??
I don’t know if it’s released yet but eventually the Medtronic pump will have the option to work with the Libre3 plus.
I think will be a Libre that’s labeled/packaged specifically for Medtronic pumps. I don’t believe users can go out and buy a normal Libre 3 plus and plug it in to the system. Not totally sure so hope this isn’t bad info.

I’ve seen some people say the new Medtronic setup is pretty promising, especially with that closed loop design, though others still swear by Dexcom G7 for its ease of use

I have a friend who is on a POD and Dexcom closed loop system and swears that it had been life altering in her D care and her entire life. She still uses the G6 despite my telling her about the ease of the G7, etc. I often woneder how people make these little decisions for themselves…for example, shes all modern and on the closed loop but still wont switch over to the G7? Ah, well…

Nice to hear from you daisymae. I was trained as an economist, and the field is populated by lots of people who wonder the same thing - and have argued about it for centuries.
W/r/t diabetes care there are so many quantifiable factors, but that just gives one more to wonder about, as you note.
I also have not made the switch from the G6 to the G7, and so you’d be puzzled w/ me as well. My reasons: initially there was a lot of disappointment because of sensor failures and i’m in a habit with the G6 - it doesn’t seem worth it to switch.
I’m sure I will be forced to switch within the year, and i will probably be as happy with the G7 as with the G6 (which is 7 or 8 on a 10 pt scale). I’m a little lazy though.

I was on the Medtronic with guardian CGS. This was 10+ years ago. My doctor recommended the TandemTSlim along with the Dexcom G6(5?). It was so much more accurate than the Medtronic Guardian. Maybe ithe Guardisn has improved but the Dexcom is very accurate . I have not switched to the G 7 yet

I am waiting for my warrenty to expire and then i am switching from the Medtronic to the TandemSlim with my Dexcom G7. (I LOVE it! and such an improvefment from the G4, G5 and G6) My Endo has been encouraging me to consider the newest edition of the Guardian claiming that it is MUCH more accurate that models past. He is a T1D wearing a Medtronic himself and test drives all the different equiptment out their on himself. Interesting guy. Currently he is testing out both the Guardian and the Dexcom on the same arm and he claims that he is finding excellent accuracy from the Guardian. Who knows.`

Very cool to hear he is trying them and not based on a company sales pitch.

I use the Medtronic 780G currently. I used the previous Medtronic model before that, the 670G, and the 780G is noticeably much better in its algorithm and ease of use. The sensor is surprisingly accurate and it does auto corrections. I’m quite happy with it. I’ve been writing a lot about it on my blog insulinpumplife.com if you want to read more.

I cannot tell you how much i appreciate learning about your personal experience with these models. This is exactly what my endo would like me to try out. I was going to go with the route of using my G7 Dexcom with the Tandom Pump (T-Slim, I think?). He, too, likes the algorithms as you have expressed. I have been on the Medtronic Pumps for over 25 yrs now. My favorite one was the Paradigm , which was sadly discontinued. Apparently, many users complained about this as it was so popular. Currently I am on the 670G and i absolutely HATE it!!! A total waste I unfortunately committed myself to almost 6 yrs ago. And, bc I am on Medicare, my coverage wont allow me to switch pumps until the warrenty ends (after 6. yrs), so I cannot make any changes now. Bummer.
Please share as much as you can about your system. I am looking to go fwd with a closed loop system and relax a little on all the work i put into managing everything with my current crummy pump!!!

The automatic systems; hybrid closed loop (which is I think what yall are talking about) and full closed loop (no bolus) really are life changing for all of us. Some of us can do all that stuff ourselves but it means continuously monitoring the CGM (like up to every 3 minutes with the Libre IRC) and responding instantly with appropriate correction boluses, or so controlling carb and lifestyle that this isn’t necessary.
In fact latter can be done on MDI and, indeed, SDI. Some of us have done it and lived to be 90 in the past.
The life change is the AI: The computer that does all that meaningless book keeping for us and allows us to get on with our lives. The life change is not to be controlled by diabetes but to control diabetes.
It really doesn’t matter what system it is; just complain when it doesn’t work. When you eat what you want and it doesn’t correct your blood sugar. File a bug report.
A closed loop system is one that does not need our input; it just does it. A hybrid closed loop system is one that does the same but needs help for large carbs. I use a hybrid and I bolus about about 20g. 6.4% YDMMV.

Switching from the Medtronic 670G to the 780G insulin pump has brought major improvements in allowing me to spend less time thinking about diabetes.
The biggest benefit? Fewer finger pricks. With the Guardian 4 CGM, calibration is now minimal—typically just 1–2 times per week instead of every 12 hours. Calibration is entirely optional too – this pump feels like it lets ME control my life and choose when to test. This reduction has eased daily management and allowed my fingers to heal.
The CGM accuracy has been excellent, often needing just a single calibration to stay precise. The 780G also provides automatic correction boluses, helping fine-tune blood sugar without constant intervention. While I still keep a glucose meter on hand for backup or verification during lows, I now spend less time micromanaging and more time simply living. This pump has improved my comfort, confidence, and overall quality of life.
I’ve written over a dozen blog posts about this pump. They’re all available here: Medtronic 780G Insulin Pump – Insulin Pump Life
Happy to answer any specific questions

I recall being compensated for my testimonial when first starting the 670g.
Is Medtronic still offering rebates for public praise of the 780?
