I've done the stubborn thing of taking several corrections via pump for a high BG with no results. I usually do change a site after the second correction doesn't work. I just hate correcting by syringe because if that brings my BG down, I still won't know if my set is bad. I know, I know - why not just change it anyway if I'm not sure. Just stubborn that way.

You should really learn to insert manually. I don't know what set you're using but if it's a 90 degree set, it's no different than giving yourself an injection. 1-2-3 and you're done. I still feel a little squeamish sometimes when I insert the Silhouette manually, but I grit my teeth and push it in anyway. And I always change the set after 3 days. I've heard too many horror stories about infected sites and people being admitted for a bad infection. I don't want to go to the ER, never mind having to be admitted.

Oh, and you should also call Minimed and tell them that your serter is lost (or just tell them it jammed) and see if they'll send you another for free, so you can have a backup. They were good about sending me a new serter overnight after my original Quickserter jammed. When I asked to try a sample of the Silhouettes, they sent me 3 sets and a serter for free, which quickly jammed. I called and they sent me another one, free, overnight delivery.
I do insert manually, though. When I started pumping I was using Quick-Sets and wouldn't do it without the serter. One day after having several sets go bad (kinked cannulas) I just slapped a new set into my abdomen, and it was much easier than using the serter. I then switched to Silhouettes because the Quick-Sets would not work for me. I used that serter, which was scarier looking than the set itself. I used it for a few months and then had to do one manually when the serter jammed.
