hi, my sensor stopped working after 6days. It was showing LO constantly, I didn't check my blood and just ate all the usual sugary stuff. When I checked my blood it was sky high. It continued to show LO. I rang the help line and they sent a replacement but didn't tell me I had to return the sensor so I threw it away!! Now I have received an envelope so I can send it back. Going to grovel about in the bin to see if I can find it. Just want to warn other people that they need the sensor back. I didn't even think about it. Have emailed them to let them know.
I also find that when you are 'low' there is a lot of difference in the readings. Now I go back to testing blood if I'm low.
