We're elidgible for a new pump. We're using a Medtronic and they want us to upgrade to a 530G + enlite. We're thinking 530G + dex due to the reviews of the elite. These are older than a year so I'm curious if they are still accurate. We're leaning to 530 + dex, we like the Medtronic pump & have had great functioning hardware & service. Thought?
