‘DexCom’ Stock Deserves To Be Punished Given That Their ‘G7 Sensor’ Is Remarkably Inaccurate.

I have worn eight (8) Dexcom G7 sensors — for a total of around 75 days. It is NOT the full 80 you would expect (i.e., 10-day lifespan x 8) because I threw away a couple BEFORE they expired because they were so, so, so inaccurate. There is NO point, whatsoever, of wearing an inaccurate blood glucose monitor. Actually it is harmful — even DANGEROUS. You are being given FAKE RESULTS. What the G7 reports is NOT your actual blood glucose level. Much of the time it is just a RANDOM NUMBER.

I just couldn’t believe HOW INACCURATE the readings were. They were bad. Many times they were not even in the same ballpark. Crazy. Stupid. DANGEROUS. Harmful. Should NOT be allowed. I gave up on the G7. Will never get a DexCom product again. I spent HOURS calling and talking to their support. I bought 3 sensors (for $320 of my OWN money (since it was not covered by insurance) & DexCom support sent me FIVE (5) as replacements because they ‘acknowledged’ that I had DUFF sensors. That is how I ended up with 8 sensors. Dexcom has all my data & knows they screwed up. Hence the 5 free sensors.

You know that old chestnut how a totally broken watch, that doesn’t run, is better than a watch which is 1 second too slow/fast BECAUSE the broken watch AT LEAST shows the correct time TWICE a DAY whereas the slightly inaccurate one NEVER (ever) shows the right time. That is the story with the DexCom G7. Much of the time it just generates garbage results.

Please be warned.
