I test with a Nexus Meter and a Contour Next Meter Threy never agree and can be as much as .8 different.I t makes me wonder whether it is worth doing.
 
I agree with @bulkbiker .
They should both be within 15% accuracy of the correct value but they could be out in opposite directions.
You may find they differ more at higher BG levels - it's the nature of percentages.
The better your control, the less difference.
 
I agree with the others. Put one away as an emergency back up. Just use one or you will be forever confused.
 
0.8 is nothing to worry about on the meters. There is a 20% tolerance allowed on the actual readings. Obviously the higher your bloods then the bigger the difference. Stay with 1 meter and put the other meter away as a back up

I think you will find it is was 15% from the ISO 2013 guidelines.

Accuracy standards set to improve
By the end of May 2016, new standards are being implemented to ensure that blood glucose meters meet stricter accuracy standards.

Under the new standard, meters will need to meet the accuracy guidelines 95% of the time:
  • Within± 0.83 mmol/L of laboratory results at concentrations of under 5.6 mmol/L
  • Within ± 15% of laboratory results at concentrations of 5.6 mmol/L or more
