I was advised about the control solution testing. My complaints: My meter has testing on it from 2024 which supposedly you cannot delete - you can hide. Your test strips are very wasteful, inconvenient, & expensive - individually wrapped - why not a tube like regular glucose test strips? Lastly you charge more for the Ketone test strips but the meter does not tell you which strip to insert so I insert the glucose test strip and it says Ketone after I insert it. Go thru both both testing then start new test with the Ketone strip and after I insert it says glucose. I have checked the reading both ways and against my regular glucose reader and it doesn't seem to matter what test strip you use for the readings - Kwtone or Glucose, so why charge more for the Ketone strips?
