I also use the Insight, been on it for 5 months (been pumping for 4.5 yrs). I really like it, it has a few quirks like taking care not to plug it into too high a power USB adaptor when charging, it is a bit slow but it does cope with multiple bolus's, choose a Samsung phone charger if your going to charge in your car. Handset needs charging every few days and while its on charge you cannot use it. You can speed up the handset up by resetting it weekly (just hold power button down for 5 secs). Moving to a pump was the best choice I ever made.
