Tslim or medtronics

I used Medtronic from 1985 until October of 2020. At that time I switched from the 670g to the tandem/Dexcom system with control IQ. I initially balked about how long it took to fill the new pump but when my A1C went down over 2 full points, I was sold. I am now so thrilled to be on it! There was definitely a bit of a learning curve but well worth it. The Dexcom alone is reason enough to make the change!
