FreeStyle Libre 2 Sensor
Take control over glucose monitoring like never before with the Freestyle Libre 2 Sensor!
The Libre 2 enables the user to obtain continuous, discrete blood glucose readings without the constant hassle of carrying and disposing of lancets and test strips. The Freestyle Libre 2 is a Flash CGM (Continuous Glucose Monitoring) system that is worn on the back of the arm and automatically tracks glucose levels day and night.
The Libre 2 system has two simple components: (1) sensor and (2) reader or a compatible smartphone. The sensor placed on the body will send continuous readings to the user’s Libre 2 Reader or paired smartphone.
Why Flash Glucose Monitoring System?
The Freestyle Libre 2 system is one of the only glucose monitoring devices to measure glucose levels every minute. When combined with the libre 2 sensor, nearly unmatched levels of accuracy in a wearable CGM are provided. This means that a total of 1,440 readings per day ensure the user is always aware and in control. An optional audible alarm notifies the user through the Libre 2 reader. With a simple swipe of the device real-time measurements and trends are viewable.

The 3 is smaller the the 2 and you do not have to scan it with your phone for a reading, it automatically syncs, which was nice

Quick and easy to put on, nearly painless and easy to use and install app

This is my first time trying the libre 2. It seems to be working just like the libre 3 plus the benefits of the slimmer style. I look forward to ordering it again ! I like to put the patch over it, so I am not nervous about it falling off.

My father was diagnosed with Diabetes in October and seeing him pricking his fingers was truly awful to me. He also works with his hands as a jeweler and it was becoming uncomfortable for him to do that twice a day. Since the end of October I've been purchasing these for my father I will never let him go back to anything else

It works very well. The only bad thing I can say about it is if it’s placed in the right spot it won’t work right. The instructions are very clear to where you need to place it
