Hey everyone! I've been pumping with MM722 for three yrs now and finally purchased the minilink. I can't get in for training at my endo's office for 3 more weeks and I just couldn't wait, so I went ahead and started myself. So far so good I think. Between the training video and booklets that came with the pump and all the helpful advice found on this site I'm up and running without a glitch, so far. I found the sensor insertion no more painful than an infusion set insertion but the anxiety prior to pushing the button on the serter was brutal. I actually broke out in a sweat! LOL! Anyways, I'm very impressed with it so far!
