not me personally, but my boyfriend has been on the pump for 3 months now.
the type of infusion set he has is nice. at first it let circles where the adhesive was, but his skin has gotten used to it now. the needles/caths leave prick marks for a bit, but slow healing comes with diabetes.
let me know if you have any questions. i've been along the whole journey with him, but if i dont know something, i can always ask him.
