Absolutely worth it. It took a month of back and forth paperwork between my doctor, insurance, and the medical supply company, but now that I have it, I have a much easier time monitoring my blood sugar. My package came with two transmitters, a 6 month supply of sensors, and two handy little receivers.
Buyer beware though, if you intend to setup the Dexcom app on your phone, be advised that Dexcom DOES NOT SUPPORT all phones. Check their device compatibility list on their site first My OnePlus6T on Android 9 is not supported.
Fortunately, the amazing devs at xdrip have been able to make xdrip work with my Dexcom G6 so I finally have real time monitoring on my phone and on my watch. I now have the tools to be on constant watch of my blood sugar levels and can adjust my habits accordingly. From eating a banana to bump it up, or something simple like getting up and walking to lower it… The CGM monitor will change your life. Go for it!!!
