Hello Tom, I have been wearing Dexcom G6 for over a year since I’m elderly and have nighttime lows with T1. One of the things you didn’t discuss with the meter is the ability to set alerts with the app with family members. This is wonderful as I can live on my own and if I get a low in the middle of the night, my daughter is notified by phone. If I don’t respond, she can either call 911 or come to my home depending on how low the reading is.

Next, you stated the Dexcom G6 can’t be worn except on the abdomen in the US. I have been wearing mine on my arm and abdomen with no difference in reading accuracy.

Finally, as for accuracy, I have never had any issues with accuracy, even on the first day change. I assure this by checking with a meter against the readings, especially when low or high.

I hope these notes help add to your information. Blessings

My family and I attended a mini-workshop at our local pharmacy and found out that the Libre sensor can be inserted 1 - 2 days before it is activated without losing any work time. This little tip was shared by a diabetic Dr who found she got better accuracy on Day 1 by doing this.
Sadly, here in Australia, we haven't seen Libre 2 yet.
Thanks for all of the helpful information you share.

WoW!!! I guess you can tell how impressed everybody is with the quality of your work here. I'm blown away -- fantastic review, and really appreciated -- thank you.

[brittanycowling]

Thank you very much for making this video. My little girl was just diagnosed as a type 1 diabetic and we are still in research mode for monitors. This was so helpful!

[duygukorkmaz]

It feels like a relief when someone compares products from own experience. Thanks a lot!

[boatman]

FWIW I would rate this comparison review of the Dexcom G6 and Freestyle Libre 2 10 out of 10! Your comprehensive and highly detailed description of the pluses and minuses of each system is just what the doctor should have ordered but didn't. Thanks for all your hard work, much appreciated!

[RamaDrama]

Thanks a ton! Loved your comprehensive comparison and enormous amount of info without making it feel tedious.

[gigiwong]

It's a really long video and very comprehensive! Thanks for your great effort!

[soheilastrunk]

Thank you! Im newly t1 diabetic and have been trying to figure out which one would be best for me. This helped so much. Keep up the great work!

[karliholkko]

Thank you for this very helpful video! I am a parent of a newly diagnosed child with type I diabetes and we are starting the Dexcom G6 today. Will continue to watch for more videos! Thanks again.

[KentuckyWaterfall]

Your videos are very informative, keep up the good and helpful work!! You help more than you know.

Thank you for posting this. I have been on the Libre 2 for 4 weeks now and I have enjoyed not sticking my fingers, the video you did telling us how long before you eat should you take you fast acting insulin to stop the highs and lows. I started taking mine 20 to 30 min before and My libre stays in the ranges. I was debating on the dexcom but went with the libre2 for one it last longer and for right now my Medicare pays for it 100%.

I use the Free Style Libre and was able to manage my blood sugar and get off my medication. I still wear and has been a life saver

[donjohnston]

I am T2D and bought the Dexcom G6. From the get go, I was able to see I where my diet needed to change, especially at breakfast. I also wanted to get an idea where my BS is at when doing physical activity like 2-3 hour bicycle rides. I recommend potential purchasers review this video prior to purchase.

[gregobrien]

Outstanding job comparing these two CPM. I swear you look like a younger version of me

[stbufraba]

Great video. By the way: I've been using Libre 2 since June 2019, my wife uses Dexcom G6. We both don't want to switch.

[stevewells]

Am loving the SIBIONICS you turned me onto - many thanks.

[bigjoeblanton]

Just want to say thank you for such an amazing review video. By far, the best I’ve ever seen on YouTube on any topic.

[williamloring]

I have used both systems; switched from Libre2 to Dexcom6 because too many Libre sensors either died early nor fell off. I generally agree with your ratings, but consider the Dexcom a little easier to attach -- a) arthritis made it difficult for me to unscrew the container and b) upper arm location was awkward to push against the spring for attachment. Dexcom's location (abdomen) made it easy to see what I was doing and push-button for attachment was also easy. Also in past 9 months only one Dexcom sensor has failed early and that was by less than a day.
