This guy is my new favorite poster on this forum!
I do have to say, in his defense, I was talking to a nurse with over 30 yrs experience who said I was being wasteful in putting a fresh needle on my pep-pen before every injection. According to her, "nobody" in the diabetic area of healthcare does that. Slap a needle on, use it till the pen is dead, pitch it, and grab another pen and needle.
Further to that end, this morning I noticed when pricing cartridges on a diabetic supplies website, their "package" deal was 10 carts, and, surprise, 10 needles.
Maybe this guy is on to something?
Still a tool, though.
