Article Highlights
The t:slim X2 is a tubed insulin pump designed for users who value both innovation and reliability. Its full-colour touchscreen, rechargeable battery, and intuitive interface make it feel more like a smartphone than a medical device.
When paired with a Dexcom CGM, Control-IQ activates a hybrid closed-loop algorithm that automatically adjusts basal rates and delivers small correction boluses throughout the day and night. The result is fewer highs and lows and less manual management.
The t:slim X2 is designed with real-life needs in mind, combining durability, connectivity, and user comfort:
- Slim touchscreen design: Modern, full-colour interface that is fast and intuitive
- Large insulin capacity: 300-unit cartridge for higher insulin requirements
- Rechargeable power: Lithium-polymer battery (charges about every 5–7 days)
- Watertight protection: Rated IP27 (up to 3 ft or 0.9 m for 30 minutes, not swim-proof)
- Smart connectivity: Bluetooth for CGM and smartphone integration
- Durable and discreet: Compact (112 g), designed for daily comfort
The t:slim X2 with Control-IQ is approved for people who meet certain medical and age criteria.
Approved for:
- Ages 6 years and older with type 1 diabetes (Control-IQ)
- Pump alone: ages 6 and older without Control-IQ
Requirements:
- Minimum 10 units of insulin per day
- Minimum 25 kg (55 lb) body weight
Not suitable for:
- Children under 6 years old (for Control-IQ)
- Pregnant women
- People on dialysis or who are critically ill
- Users taking hydroxyurea
You'll need to:
- Check glucose as directed by your healthcare provider
- Accurately count carbohydrates
- Maintain regular follow-up visits
- Have sufficient vision or hearing to recognize pump alerts
Control-IQ technology continuously predicts glucose trends 30 minutes ahead and adjusts insulin delivery every 5 minutes to help keep you in range. The system is designed to learn your unique needs and adapt automatically over time.
- Learns your needs: Predictive modeling adapts to your glucose patterns
- Prevents highs and lows: Delivers auto-correction boluses (up to once per hour) and suspends insulin if a low is predicted
- Adapts to your routine: Sleep and exercise modes adjust targets
- Keeps you in control: You still enter meals and confirm boluses
The t:connect mobile app and Tandem Source platform make it easy to view and manage your data. Together, they give you and your healthcare team better insight into your glucose trends and insulin delivery patterns.
- View insulin, CGM, and pump data from a single dashboard
- Sync automatically to Tandem Source for cloud review
- Gain data-driven insights for you and your care team
- Software updates are done via computer connection, not over the air
Clinical and real-world studies consistently show that Control-IQ technology improves glucose control and quality of life for users.
Reported averages include:
- Around +11% time in range compared to standard pump therapy
- Fewer low and high events, especially overnight
- Improved A1C and reduced daily stress

Before choosing the t:slim X2, it's important to understand what daily use involves. The pump recharges every five to seven days and uses a tubed design that many find reliable. Control-IQ requires a Dexcom CGM connection but continues basal delivery if the signal is lost. Coverage varies by province and insurance plan, so confirm eligibility before purchase. Users complete a short online training (about 30–45 minutes) before starting, and infusion sets are changed every two to three days for consistent insulin delivery.
The t:slim X2 may be a strong option for individuals who:
- Want proven automation: Control-IQ algorithm adjusts insulin every five minutes
- Use a Dexcom G6 or G7
- Prefer a rechargeable pump
- Need a large reservoir (300 units)
- Value app connectivity and cloud data sharing
Switching to an insulin pump is a structured process that involves support from both your healthcare team and Tandem's training program:
- Talk to your healthcare team to get a prescription and referral
- Verify coverage with your insurer or provincial program
- Request information at tandemdiabetes.ca or through a diabetes clinic
- Complete training through an online learning module (about 30–45 minutes)
- Start with support from your educator and Tandem's team to optimize your settings
The typical timeline from consultation to active use is about one to three months, though it can take longer depending on funding approval, clinic scheduling, and individual circumstances.
