    The pump loses its Automode connection constantly. It’s been a nightmare. Calling tech support constantly.

    I agree with David. I calibrated at 10:30 pm and it woke me up at 3:48 am to enter blood glucose to stay in auto mode when there was no reason for pump to not stay in auto mode. Also you have to be precise to stay within range. Goo luck if you miscount carbs and you sugar goes high. While pump target is set to 120 for auto mode it will only correct for 150. If 120 is target the pump should correct for 120 not 150. It’s very frustrating. My guess is I will have to drop auto mode and go back to manual mode. Oh and the Medtronic sensor has a range of 33%. That’s right, it is allowed to be 33% off so you can’t really trust what you see on your screen. I tested 6 times a day before 670g and there are days I have to test more due to auto mode. Get ready to ration your test strips.
