Free Freestyle 2 is designed for those who need to control their glucose daily. But what if someone proves it In medical terms you do not need it? On this new 24/7 of the Xataka YouTube channel, we have used it for more than a week to understand what it contains to live with that level of continuous control… even when there is no diagnosis behind.
Mario Arroyo has used it for more than seven days in various situations: from a copious meal to a paddle game or a night with unexpected drops. “Oysters! Eh, no pain, no pain.” The reaction was spontaneous and encapsulated the tone of a test that did not aim to issue medical trials, but rather observe how such a device behaves outside the usual context.
Freestyle Libre 2: Live with a 24-Hour Glucose Sensor
The first thing that impresses with Free Freestyle 2 is its appearance . Upon opening the package and seeing the applicator, our partner’s reaction was clear: “God, what a piece of needle!” However, that feeling vanished as soon as it was applied. The process is quick and painless. For a full week, it even went unnoticed during sleep, exercise, and showers. What initially seemed invasive turned out to be remarkably comfortable .
The sport also left its mark. After two hours of paddle tennis, the glucose level plummeted: from a normal value to only 57 mg/dl. A similar drop also occurred at night, where several declines were detected without any apparent cause. Three possibilities emerged: a soft diet due to illness, potential inaccuracies in the sensor readings, or, ultimately, a natural body response. At that point, the tool ceased being merely a curiosity. To what extent can we trust its alerts?
Synchronizing the sensor with a mobile device is as simple as nearing it for a few seconds. The app updates every minute, displaying the current glucose value and its trend through arrows. Additionally, it keeps a record and allows you to consult the maximum and minimum daily levels. While it’s a tool primarily designed for those who need to monitor their glucose, its clarity makes it accessible for any user. What information does this constant monitoring provide if one doesn’t rely on it?
After consuming a “normal” dish consisting of about 70 grams of turkey rice, the glucose peaked at 168 mg/dl. Although within expected limits, the rapid rise and fluctuation captured attention. Measuring glucose levels before, right after, and two hours later provided visual insight into how the body responds to different foods. With the sensor, what was previously invisible has now become visible in real time.
The sensor comes with an error margin of approximately 9.2%, according to the manufacturer—a reasonable figure for a non-medical device. However, the cost is quite another matter. The price can be a significant barrier. Therefore, the question arises: Is it a useful tool for everyone or just for specific profiles?
After more than seven days with the sensor, the overall experience has been positive yet nuanced. Mario stated: “It seems to be a very comfortable device,” while also acknowledging, “If you do not have a real problem with diabetes, its usefulness is somewhat limited.” The technology works effectively and provides insightful data, but the complete analysis—with all the details—can be found in the latest video on our YouTube channel.
