Less than optimum. The cam is less than satisfactory. I receive a specified amount every 3 months. At least 2 of the ace airs are defective to calibrate or at defective in the 12 I receive. I did not experience this with my decom 5 which is not compatible with Medtronic’s pump. When I send them back they supplied me with obligatory 2 for a lifetime and do not respond to my return which my medical doctor instructed me to do. I love the pump hate the reliability and accuracy of the latest content.
