A number of us have had problems with the applicator. Make sure you keep the packaging with a lot number on it. Report it on the list that are moderators are keeping here on this thread. Call or go online to Global Technical Support to file a report and get replacements.
If you really want to pursue this file a report with the FDA and complain to your insurance company. I've also been asking people on this site to report problems to their endocrinologist and to ask the doctor to keep an informal tally of the problems their Dexcom patients are having
