The Tandem t:slim X2 isn’t just another insulin pump — it’s a hybrid closed-loop system designed to lighten the daily burden of managing diabetes. With Control-IQ technology built in and seamless Libre 3 Plus and Dexcom G6/G7 integration, the pump automatically adjusts insulin in the background, helping users spend more time in range without constant micromanagement.

One of the standout features is how proactive the pump is. Automated correction boluses, predictive low glucose suspension, and customizable alerts make it easier to catch highs and prevent lows before they derail your day. For people who live busy, unpredictable lives, that means less stress and fewer interruptions.

The t:connect app adds another layer of convenience, letting users discreetly check glucose and insulin trends and delivering insulin from their smartphone without pulling out the pump. It’s small details like this that make the t:slim X2 practical in everyday situations — whether you’re at work, school, or out running errands.

Take our podcast guest Mary Williams, a 5th-grade teacher living with type 1 diabetes. In her classroom, she relies on the t:slim X2 to quietly handle much of the background work of diabetes management. The alerts keep her on top of highs and lows while she’s teaching, and the app gives her quick access to data without breaking the flow of class. For Mary, the result is more focus on her students, and less time worrying about diabetes.

I sat down with Mary to talk through her experience — from classroom strategies to her favorite features of the pump. You can watch the full interview on YouTube or listen to the podcast episode for the full conversation.
