I really wanted these to work because I liked the designs and initially felt confident they would help protect my Dexcom G7 sensor. I first purchased directly from the company’s website to test them out and was excited to later see them available on Amazon. Unfortunately, neither experience matched the advertised performance. The biggest disappointment was the adhesive. In my experience, the overpatch started lifting after about 3 days and neither patch stayed securely adhered for more than 7 days total. That falls far short of the “15+ day hold” claim listed in the product description. When the patch was first applied, it looked great and felt secure, which made the eventual lifting even more frustrating. I really wanted to continue using these because the patterns and overall appearance are appealing, but reliability matters most for a CGM overpatch. Based on my experience, the adhesive simply did not deliver the long-lasting hold that was promised.

Hi Jessica, thank you for such a thoughtful, detailed review, and for giving us a real chance both on our site and on Amazon. We're so glad the designs caught your eye, but we're sorry the hold time on your Dexcom G7 overpatch didn't come close to matching it. Our patches are tested to hold from 7-15 days with proper prep and placement, so a lift at day 3 and full separation by day 7 tells us something specific to your application we can help troubleshoot, not what you should expect from us. We'd like to send you a fresh pack from a different batch along with a quick walkthrough on placement and skin prep so you can actually get the reliability to match the look. We have reached out via email, so we can get that sorted for you right away!
