The Stelo is based on the Dexcom technology. The Dexcom is the gold standard for CGM monitoring. You can calibrate it to ensure accurate readings that align with the glucose in your blood (not just interstitial fluid). Some in the DDF groups skipped that important step..capillary(fingerprick), Interstitial (CGM) and venous blood (lab) are consistently different and need to be calibrated.

Abbott Freestyle is the cheaper line, and that offers a 2 week trial (Lingo) but does not have ability to be calibrated. Known as less reliable. Then some do not understand how to use BG readings beyond checking the glucose response after eating. If your goal is to lose body fat and manage your risk of all the diseases related to energy toxicity, then the power of measuring your blood sugars lies in managing your blood sugar levels BEFORE you eat.
