We are in our 60's as well😉 and my husband is the one with blood sugar level issues. Our experience with and research of All the CGM's has been very "enlightening" to say the least. There have been many false "high" sugar readings when comparing to the finger stick to verify. Vigorous exercise or Vibration like when using the roto-Tiller for example caused the entire day of Scans to show false lows. Not hypoglycaemic lows, just severe # drops which at first we were excited about. But then, to verify, he did a finger stick and there was a 40 point difference! That's pretty substantial ! Caused me to do deep research from users of these products and also various Diabetes information sites having no connection to the products... and found the truth about the need and the inaccuracies of these monitors. Very sad, really, considering the many people depending on them. I would suggest you do your own research., Staying away from any who are promoting or comparing these products. - As for us, the proof I found about the immediate accuracy of 0.08 (being almost 100%) for the finger Stick VS a 15-20 % for the monitor reading to be more than enough proof Where my husbands health is Concerned. Don'twaste the money on a new phone or the monitors. Stick to the old fashioned prooved way !
