Abbott freestyle Libre distributors under Medicare

Does anyone find them very great or substandard by now? I was able to get 30 days of senors one, but 90 days sensors from another. Also, not sure internal records kept on doctor/nurse replies to them. Also, some slow to answer phone. It seems for now medicare only pays this if you use distributors, not local drug stores in city.

Has been excellent - not one problem since medicare approved the libre

a 90 day re-order is usually less then a 90 second phone call
