I use a Freestyle Libre sensor and I like it better than finger sticks. When I was doing finger sticks I was averaging 4 tests a day; before each meal and at bedtime. With the Freestyle Libre I'm checking my glucose an average of 20 times a day. But the Freestyle Libre sensors are quite expensive. I have insurance so my out of pocket expenses are very low, but my provider bills $1074 for 2 sensors, which last for 4 weeks.
I have read comments from other posts that buyers without insurance can get sensors for substantially less, but they are still quite expensive. When I was doing finger sticks I could get enough test strips for a month for about $30.
