  I have in the last 3 times getting my sensors filled, at least 1 to 2 were bad, Dexcom will only replace 3 so I am thinking of trying another brand, I see that alot of people are having the same problem as me, This *****. At first it was amazing but not now as I have to worry if my sensor will just stop working all the time. It sounds like they sent out batches that were bad.

  I have spent over $750 with this company. The products I received from them had a 50% fail rate. Some of these they replaced but several others they denied claims to replace them. With a $100/month price tag you would hope they would do better than this. **************** is limited and a common response is that they do not divulge information on why they are not replacing a sensor. It's "against their policy" I will not buy their products again and am sorely disappointed in the company because when the product works it is a great tool for managing diabetes.

  $60 for 2 sensors that only last 8 days for each one. And I have Bluecross Blueshield, and it's actually MORE expensive with the insurance. **************** is awful. HORRIBLE PRODUCT!

  I had 3 of the last 9 I ordered fail. 2 of them back to back, and one didnt even inject properly as the wire that was supposed to be internal was sticking out of the top of the sensor. I asked to speak to someone higher up about the issue and had to call back 5 times because when they transfer you to a supervisor they send you to their voicemail who which isnt even in service so the system just says thanks for calling, goodbye. I never even got to a supervisor. I had one rep hang up on me the moment I told her Im calling for the 4th time because it never actually transfers to the supervisor. I am going to be calling my insurance and reporting Dexcom to them for faulty products and mismanagement. As well as requesting a charge back. I will be switching to a competitor from this point on. This isnt a rare case either, 2 or 3 of each of my shipments will fail. Ive had **** completely mishandle my cases, file them incorrectly and outrite lie about them. I believed in this company so much I bought shares back when I first got their product. However every year since then its gotten worse and worse and the stock prices it. Its down to half its value since 2021. There are plenty of people getting into the *** space and I highly recommend you consider them heavily over Dexcom.

  There are no words to express what terrible products this company produces. I will never work with this company again. The G7 monitor consistently would not deploy for me even when another person attempted to push the button for me.

  Why does Dexcom require serial numbers for replacements when they only put them on the boxes, and then expect you to have every single detail? The G7 has been so faulty lately, and the customer service is TERRIBLE! ********************** needs to get it together.

  One after another the Dexcom G7 keeps failing over and over!!! Why is this thing being sold in the ***??? This thing should be kept in ***** where it belongs, Not in the ***!!! I call them over and over each time the sensor fails! I am not the only one with some kind of issue! It's all over the web!

  This is the worst product ever, it fell out of my partners arm after a day and mine has stopped working on day 7. **************** refuses to be helpful and keeps putting me in a circle. The product does not work, its inaccurate and now just reads a false reading lower than 70.

  Dexcom G7 Is Failing Type 1 Diabetics And Its Dangerous As a type 1 diabetic, my life depends on accurate, real-time blood glucose data. Thats why I use a continuous glucose monitor (CGM) specifically, the Dexcom G7. But after months of repeated failures and frustration, its time to say what too many people are afraid to: this product is unreliable, unsafe, and Dexcom is failing its customers.Let me be clear:Out of 11 sensors, only ONE has lasted the full 10-day wear period without issues. Thats a 1-in-11 success rate for a life-saving medical device. That is unacceptable.CGMs are not fitness trackers. They are essential tools used to avoid seizures, comas, and even death. When sensors fail, we are flying blind. And its happening over and over ******** make things worse, Dexcoms customer service is completely broken. The representatives are often difficult to understand and seem poorly trained. Most calls end with another faulty sensor being mailed out, as if throwing hardware at the problem will fix it. Theres no real investigation, no ownership, no urgency. Just the same frustrating loop.This is not an isolated incident. Its a pattern. And its dangerous.What makes it even more frustrating is that Dexcom is a company people are told to trust. Doctors recommend it. Ads praise it. But in reality, this system is failing, and Dexcom isnt doing nearly enough to make it right.If Dexcom cant deliver a CGM that consistently works with proper support behind it then the Dexcom G7 should not be on the ********* not just venting. Im warning others. If youre using the G7 and experiencing similar issues, speak out. File a complaint. Tell your doctor. Report it to the **** MedWatch system. Our lives are on the line and silence only protects the company, not the people its supposed to serve.We deserve better. Angry Type 1 Diabetic

  My current device was started on June 14th. The session ended early on June 22nd.The device was unreliable since insertion. It consistently had sensor/session errors, and in addition it was always about 60 points lower than a finger stick. I originally completed a form through the ** chatbot to inform of the sensor interruptions and the inaccuracy of the readings. The ** bot declined my request for a product replacement.I dealt with the device for a week and relied on finger stick testing for a week for accurate data.And now after giving false readings for a week, the device has malfunctioned so poorly that it's not even working at all, and it ended the session early!These devices are supposed to last around 15 days. This one lasted 8. That's almost a 50% reduction in longevity!The device keeps prompting for a pair, I tell it to pair, and it continually won't. And in the meantime I have paid $45 for a product that I now cannot use and did not get full use out of.I submitted a case through your system, and it rejected it.I called customer support and spoke with a woman who was extremely unhelpful and told me that if the ** bot had rejected my case, there was nothing she could do. Why is she even there, then?This device malfunctioned. Please issue a replacement. I do not expect to spend $45 for a two-week sensor to only have it last 1 week, and even when it was functioning for those eight days, it wasn't working ************* should know that I have currently canceled my subscription. The treatment that I have received is unacceptable. This is unacceptable customer service. Your product failed, and not because of anything that I did. I have used these devices for a long time, I know what I'm doing, I did not do anything to cause the session to end early.I am owed a replacement. You need to make this right.
