Amazon Glucometer recs?

My insurance just denied my prescription for the Dexcom G6 (because I’m not being prescribed insulin with it). Everything is taking so long to get approved and I’m just starting to worry. It feels like no one is taking this seriously and at this point, I’m feeling silly for taking it so seriously. Anyway, until the doctor and insurance can figure their s*** out, does anyone have recommendations for a glucometer I can I order from Amazon? Sorry for the rant, thank you in advance for the help!
