I seldom (as in years-apart) have “no delivery” issues and that’s because I only use Sure-T sets. Today I did get one, and thankfully, it was about 2 hours before I’m scheduled to leave home for a few hours. Delivery issues were a bane of my existence when I used Quick Sets.
I’m glad you realized it before you left for a few hours. I’ve heard about the Sure-T sets before and I always thought if I go onto a tubed pump those would be the ones I would want to try first.
