I got a sample pack from medtronic and I do believe that this is awesome. going from 18 shots in 3 days to one port change every 3 days is highly superior in my opinion.
Medtronic Iport Advance
I tried the I-Port advance, but the straight in design did not work for me. I ended up with some pretty awful bruising. At the time I was taking 5-7 shots a day so it seemed like a perfect option, but unfortunately it did not work for me. I ended up getting an Omnipod pump instead and am thrilled to only have to change sites every 80 hours and no more needles.
