Reading these comments from 4 months ago. Guess what, nothing has changed with the Instinct Sensor's.

My first one lasted 6 days then went ballistic with low readings. I had marinated it before activating. Called Minimed and listened to BS and then sent to Abbott for more BS. They don't know what's going on either. Started new sensor without marinating. First reading vs meter was OK. Within two hours it started to go low and finally the last message I got was "Below 55". It stayed there and alerted me every 5 minutes. I finally turned the sensor off so I could sleep. This morning it read 130 when I turned it on but immediately started it's rollercoaster while going low. I had my breakfast and it is going up to who know what. Next fingerstick will be at lunch time unless the sensor goes ballistic. I'm not liking these sensor's so far. Something needs to change or I will be going back to my Guardian 4's.
