Free 2 or free 3

Hello, I would like to know which of Free Style's sensors gives better results, I use free 2 but I want to know more about free 3

After trying 10 free3 that they were perfect and several free2 that took several days to adjust, I made a post saying that the 3 was much better.

But just after making that post, the free3 has begun to fail (30-40 brand less in some sections), something that had never happened to me and on top of it does not support apps to calibrate.Although it would not serve much, because when reaching the 100-70 range it fits perfectly with the glucometer.

So I don't know what to recommend.Try it yourself to see if you are lucky.

Everyone sometimes fails, I was using (it is free 2) I marked 60 of sugar and nothing to do, not noticing the drop I did in blood and I was at 92 and it is adjusted to the 40 MINS or soI already marked that glucose, we must also understand that it measures with 20 mins of delay if you are online 120-130 nothing happens but sometimes it goes up and marks you 120 from 20 MINS and you are 150 that then puts it to you, butWell, for now I use the 2 that are the ones that give the SS and I suppose that over time they will end up sending the 3 but it is a lot of jaleo, change app, etc. I do not know if the free 1 is still used or not
