We got the sample pack from Medtronic and I've used all of them, but am still not sure which I like best. Sloan doesn't like any of them, but it just works better. He has a site on his rear right now that isn't getting tugged every time he pulls his pants up and down. (I circled the tubing once around the outside area of the infusion set while the skin-tac was still tacky and then stuck tagaderm over that!) I'm wanting to order some but I'm not sure which one to get. I know there isn't really any right or wrong, I just thought I would see what most seem to use.
