    The Dexcom difference.

    When it comes to glucose monitoring, Dexcom® sets the standard for accuracy and exceptional performance. It’s no wonder Dexcom has consistently ranked #1 in customer loyalty for 6 years in a row.1

    • Superior accuracy – most accurate pump-integrated CGM available2
    • Small and discreet – thinnest and lightest sensor available
    • Comfortable – smallest introducer needle and tiny sensor wire for easy, comfortable wear
    • Longest sensor wear – up to 7 days2
  • So small, so discreet.

    The t:slim G4 Pump is very small and slim. It looks more like a smartphone than a medical device, so it’s easy to use in public without drawing attention. But don’t let the small size fool you. The t:slim G4 Pump can hold a surprisingly large amount of insulin – up to 300 units – thanks to an innovative flat insulin cartridge design.
