Hana put a new sensor on at midnight last night. We always have some off numbers The first 12 or so hours of a new sensor, however, it's been almost 24 hours now and it has not been accurate at all today. At 11 am today it said she was 46 when she was 90. Now it says she's 250 two arrows up when she's 150. There hasn't been one accurate number today. Has anyone experienced this? I'm going to change it now. Hate to do it because I have to use our last one. Our new shipment goes out tomorrow. We leave for Hawaii a week from today. I'm going to call in the morning and hopefully catch the order before it ships and ask that it it be sent 2nd day delivery.
