  It's really crazy. $20 for the glucose meter. $1 for each test strip. And you are expected to be testing yourself around 10 times per day. CGMs are much cheaper by comparison since it's a one time sensor installment for 15 days worth of monitoring. Though you are still looking at anywhere from $100/$300 per 15 day sensor. Nuts considering these sensors are literally just a metal spike hooked into a small DSP sensing the voltage and transforming it into a glucose value. The spike is coated in a thin layer of silver cloride which interacts with the glucose in the blood to make that voltage, pretty neat [1] But hard to justify that $600/month price tag when you really bust out what these little plastic boxes are actually doing.
