I thought I remembered reading about being able to samples of different infusion sets, but I don't remember where. Is that a real thing, or am I dreaming? How do I get some? Also, DS wants to try a longer tubing (for arm sites). We currently use the Quickset with 23" tubing, but I see they now offer 32" tubing. Has anyone tried it? It seems kinda long to me, but he s the one using it..... Any input is appreciated!
