Tandem t:slim X2

The Tandem t:slim X2 presents itself in 2025 as a robust tubed insulin pump with integrated touchscreen and Control-IQ+ technology for 30-minute predictions. The system automatically adjusts insulin, delivers AutoBolus, and supports special modes for sleep and exercise. With 112 grams weight at dimensions of 9.6 x 5.3 x 1.5 cm and a capacity of 300 units, it offers a slim solution with color touchscreen. Compatibility with Dexcom G6/G7 and FreeStyle Libre 2 Plus sensors (durability 10–15 days) enables iCGM functionality without finger pricks. The automatic features include auto-adjustment and missed meal correction, while software updates continuously bring new features. The precise functionality and updatability make the system particularly attractive for tech enthusiasts who value modern technology. However, the pump is not waterproof and heavier than the Mobi variant. The touchscreen can be sensitive and requires careful handling. Despite these limitations, the system significantly improves Time-in-Range (TIR) and minimizes manual interventions through its user-friendly operation and multiple CGM options. Compared to other systems, the t:slim X2 shows particular similarity to the Tandem Mobi, as both use identical technology, with the X2 being larger and featuring a touchscreen. While the X2 is better suited for desktop users with large screens, the Mobi scores through its more compact design. The MiniMed 780G also offers similar HCL capabilities and automation levels.
