Reviews Summary

Overall sentiment towards Dexcom is predominantly negative, with a majority of reviewers expressing significant dissatisfaction with both device reliability and customer support. While one review suggests STELO is beneficial for type 2 diabetics, most mention recurring device failures, unresponsive or inconsistent support channels, and shifting company policies. A single positive report highlights satisfaction with the STELO CGM, but even this is paired with a call for broader product access.

Common feedback includes frequent equipment malfunctions, with several users noting multiple failed sensors and inconsistent performance of products like the G7 and STELO. Customers repeatedly describe customer service as unhelpful, slow to respond, and unable to resolve issues efficiently, citing poor communication, vague policies, and interdepartmental confusion. Some explicitly reference financial and logistical problems, such as denied reimbursements and complicated claims processes.

Trust in Dexcom’s diabetes management technology and support is evidently strained according to these reviews. Recurring references to operational failures and a lack of accountability reinforce a reputational concern, especially as customers share frustrations experienced across different regions and situations. Overall, Dexcom is perceived as lacking reliability and consistent support for users relying on continuous glucose monitoring solutions.

Unreliable. Cheap quality and getting cheaper. As you can see in the picture, when my reading was actually 122, it showed 225. I was very suspicious, so I did the blood test. My sugar is well controlled and never goe that high. Can you imagine if I was using dexcom to determine my insulin. The problem is that they are focused on the profit not the customer or patient!

STELO is a game changer for diabetics who are not using insuline. You can purchase it over the counter, you do not need prescription to get it and price is reasonable ($99 for one month supply - 2 sensors). At the same time I recommend that manufacturer works with Medicare to get this device added to products on Medicare formulary. Anyway - I installed STELO yesterday and now I see every 15 min my blood glucose levels . This will allow me to manage my T2D much better. Thank you.

Dexcom makes it incredibly difficult to get replacement sensors. The last time I requested a replacement they couldn't figure out why it hadn't shipped, it took me calling 4 times for someone to look into it and expedite. They don't listen to any product feedback or concerns and try to shift the blame on customers for their faulty products. Very disappointing
