  G7 device keeps malfunctioning. Three failures out of four devices in less than 30 days. Support is always from overseas. Very polite, yet utterly incompetent. Their latest helpful advice is literally to switch to a different provider. What else is there to say?!

  This company is a total joke. I have no idea why providers recommend it so much. I was using the Libre Freestyle and was convinced by more than one provider that I should switch to the Dexcom because it was more accurate. I got a 3 month supply, each sensor only lasts 10 days (compared to 15 on the Libre), so I had 9 total devices. Not exaggerating, only 3 made it the whole 10 days. All 6 of the others had "sensor errors" and stopped working before the 10 days. I have been using a CGM for over 3 years now and am very familiar with how to use them, so it was not my own errors causing it. In their defense, Dexcom did replace 2 of the sensors, but their online form did not work to be able to request them so I had to call which is time consuming, and, frankly, I do not have time to be requesting replacement sensors every week. Not only are the sensors more costly than the Libre, you also need more to cover the same time frame, and 70% of them wont work properly. What a scam.

  Dexcom is a great product sometimes when they work properly, however The sensors sometimes does not have needles that insert in your skin for readings, and they fall off if you are a heavy sweater even wearing the overpatch. You call support and they ask fifty millions questions about what happen and you tell them and they dont seem to understand the process of what you tell them. Then if you have had more than three in a year to go bad, they wont replace anymore, you or your insurance will have to pay for them in order to get them replaced. How sad that Dexcom wont stand behind their products.

  I have been a dexcom user for several years in the past with no problems. However, my dexcom G6 transmitter just stopped working on 5/22/25. I called technical support and was told that they no longer have one day fed ex delivery. They said it would take 3 days. Today is the 5/29/25 and still haven't received the new transmitter. I also have not received an email with a tracking number.I have been a diabetic for over 40 years, fortunately with no side effects, but I also have ********* DX which makes controlling my diabetes very difficult and since I haven't had my cgm,I have had 3 hypoglycemic events where my wife has had to inject me with ********.There quality of care has significantly decreased over the years and it is obvious to me that they didn't care about their customers health. I would be very ***** about using dexcom in the future since I'm very concerned about my health and their ability to understand consequences of their LACK of action!

  This company needs closer review. Their product does not last the 10 days they claim. Providing you with only 3 sensors for 30 days doesn't allow for equipment failure or issues with functionality related to normal and daily activities. Their customer service is also horrible. In an emergency situation when their device fails their solution is to ship you something in 5 days. For a device that is supposed to be lifesaving how can they not have overnight delivery service. Lastly due to not following *** regulations they are now having an inventory issue leaving some with no supplies for 30 days or more

  I just got home from the hospital, after trusting the G7 .It was telling me I was at 158, but in fact I was going higher and higher. At first I thought I had caught the flu feeling worse and worse,by the time I realized it was giving false readings I loosing my balance and eyesight at 1300, still Dexcom was saying I was in the 150s.I've been a diabetic for 16 years and have never DKAed .I read that they did significant unotherised changes to the G7 and released it into production ?? .Is making more money more important than people's lives to Dexcom? I used to have a Lifestyle CGM and never had an issue. After loosing over ten pounds and gaining a huge hospital bill ,I back home trying to get back on my feet! There's probably a law suit here,I should have become a lawyer!' DONT TRUST YOUR DEXCOM G7 IT NEARLY KILLED YOU !! My doctors words. Get the Lifestyle if possible I've had both much less problems and breakdowns with Lifestyle CGM . I'm home now but not able to return to my construction job for being in the hospital bed for so long left me kinda lame and weak ,loosing more money daily. I'm all for company's making money but not when my life is on the line, why didn't Dexcom get a full *** approval before releasing the new product! DON'T TRUST THE DEXCOM G7

  *************************. Terrible customer support. They have told us multiple times that Dexcom isnt a good fit for our 3 yr old and its his fault that their trash product breaks and fails. They tell us to call our doctor every 3rd time there is an issue. IMPOSSIBLE for them to take fault for an issue and to provide a replacement. If it comes, its usually 15 days later.

  Want to be treated like you'r an idiot? Just call customer support when you have a failed sensor. My sensor stopped working after 2 days. Woke up feeling lightheaded and dizzy so looked at my monitor that lost connection 2 hrs earlier and said replace sensor. Manually checked my sugars and was at 3.6. Called customer support for replacement sensor. You'd think I was asking for her home address and bank account number. Talked to me like I was a child. I'm 55 and guessing from the voice it was someone my kids age. No replacement sensor. My advice go Libre 3. My brother uses them and hasn't had issues. So back to manual testing for 8 days and hope next sensor is going to work better. DO NOT BUY DEXCOM!!!!!!!!!!

  They did not ship my replacement sensors as promised. I had issues with the transmitter and used up my sensors trying to correct this issue. My insurance would not cover more since I had just gotten them. When I called Dexcom 10 days later and still no sensors I was told It was "still being processed." Now, I am out of sensors, no email from Dexcom as customer service promised, no offer to overnight these supplies (or at least one...) when I spoke with customer service, and customer service told me they would "escalate this up the chain." This is the first issue I have had with Dexcom, but I took them at their word and now I am very disappointed in them and their service.

  Dexcom G7 receiver, not working/pairing and under warranty. Called dexcom tech support and went through 4 sensors trying to get the receiver to work again. Dexcom G7 has a 5 year warranty and I have 2 years left on my receiver warranty. Dexcom refused to replace the receiver.
