Buy Freestyle Libre 3 CGM System 

The Freestyle Libre 3 CGM System is the perfect device for diabetics, providing you with continuous glucose readings automatically delivered to your smartphone. 

It is the smallest, most discreet sensor yet that effectively measures the glucose concentration in the body’s interstitial fluid day and night. 

The sensor can be worn for up to 14 days and is water-resistant, continuing to work when you shower, swim or exercise. 



The first thing you need to do is download and set up the app. Once you have set up the app on your smartphone you can apply the sensor. 

Wash the area where you want to apply the sensor. Once dried, unscrew the cap of the sensor applicator and put it to one side. Place the sensor applicator over your arm. Push down firmly to put the sensor onto the back of your upper arm. Listen for the click and wait for a few seconds. Gently and slowly pull the sensor applicator away from your arm.

It remains connected to the app very well. Drops out occasionally, but not often My only gripe is that I have bought 1 or 2 boxes 3 times in the last 6-8 weeks and the price has risen every time I have bought the product
