I have had a Medtronic pump for 3 years. 3 months ago suddenly more than half my set changes ended in a no delivery alarm when I bolused, or I was very unwell with ketones about 4 hours post-change. (P.S. You don't get a no delivery on basal infusion I discovered.) I was using QuickSets and changed to Silouettes and Sure-Ts and have just had yet another high BGL and then no delivery when I tried to fix it while on a brand new Sure-T.
Medtronic say "site issue" and I reluctantly agree, after much trial and error, but I am not a fan of the Silouettes - they leave a bigger hole and they are much harder to insert on my back/backside!
Has anyone else had similar problems and do they resolve? Can I ever go back to my old favourites the Quicksets?
