Many ads everywhere. Some say do not need to puncture your finger anymore. They say nothing else. They need blood to test don't they? Are they simply avoiding explaining that you puncture you arm instead?

I want to purchase a glucose testor under Medicare. But don't know which one to get. I have forgotten the members on here who have disclosed they have diabetes. So I just wanna ask the whole community which tester to get.

tks in advance
