The MiniMed CGMS is not accurate, even they say it. It has a 15 minute or so delay. I have never tried one, but I know people who have and from what I have seen, its not my cup of tea. I do like the dexcom (sp?) CGM though.
pump takes some getting used to. I don’t use any clips, I wear the pump in my back pocket and I tuck the tubing into the waist of my pants. Works best. I work with toddlers and they never notice it (they pull on it if it is out). Or I wear it in my bra, but thats not really an option for men.
I sleep with it next to me. I can not sleep with it attached to any article of clothing.
