Great stats. I’d stick with Medtronics for several reasons. They are an end to end solution, still to this date the only one. Single device along with bluetooth enabled to access the online app on the 770G model. When available, the 780G (a firmware update) using the G4 sensor has had rave reviews from the European market, where the new model is now available.
I would not base my choice of CGM based on ‘no calibrations required’ claims. We are all different and calibrations will be in our future for a while.
After 40 years of this I’ll estimate a total of 100,000 + needle sticks. The needle sticks are a way of life for us.
Yup, some of us love it!!! Perfect it isn’t, but neither am I. After upgrading from the G5 which required daily calibration, I have never once calibrated my G6. As long as my A1C/GMI stays in the mid 5 range, I am not going to worry about the occasional temporary meanderings of the G6, especially when my BG drops below 70 which causes artificially low Dexcom BG readings. Dexcom is not highly reliable for individuals with a low BMI index (under 19) that keep their BG’s below 80. This, according to Kevin Sayer (Dexcom CEO) is a known issue that is on the long-term engineering list of Dexcom to address.
But dexcom paires with tandem and works seamlessly.
It also pairs with Omni pod.
Before I went to tandem/ dexcom I tried the Medtronic and guardian combo. I wasn’t getting stable enough readings and the pump kept turning off the algorithm. I had to calibrate 3 or 4 times a day.
The tandem has its own issues, like the difficult cartridge thatyou can’t see the insulin. And dexcom with the insane amount of waste.
Still I prefer it to the Medtronic system. Let’s see how they go forward.
Thank you for your data on the Medtronic CGM. I’ve been using the 670G since 2018 and in most of that time it as worked beautifully for me. I don’t mind the fingerstick and think I’d be nuts always wondering whether it was really accurate. I find that once my G3 CGM shows me below 65, it is hard to convince it that I’m really at 75 or 82 as the Contour reads. I find that the shipments of sensors seems to play a more important role is accuracy. The last box I opened, I all five sensors crapped out on me after 5 days…it was such a pain that I was thinking I’d switch to the Dexcom, and your data helped me rethink through that. My A1C (6.1) and TIR 88-90 have been excellent for me with the Medtronic system. Thank you.
I presoak a day before inserting a new sensor but find the Dexcom G6 sensor is still not very accurate until around day 2 and then it only lasts until day 8. I have to finger prick all the time.
I was on the Medtronic 670g with Guardian 3 sensor for 4 years. I was forced to switch to Dexcom and TSlim because I went on Medicare. There are advantages and disadvantages to both systems. I would recommend anyone who has issues with CGM sensors would be to try “pre-soaking” the new sensor and try a new location. I wore both sensors side by side and used fingersticks to calibrate the Medtronic. Both sensors were close to fingerstick results. The most annoying thing about Medtronic is the calibration requirements for 1st day. The most annoying thing about Dexcom is the codes. The most annoying thing about Medtronic pump was it’s big and bulky. The most annoying thing about TSlim is it’s not waterproof and it needs to be recharged.
