How accurate is codefree meter?

I know many posters use code free meter and strips for the system's good prices but how accurate is it? I have a nipro trueyou Meter and had 1xtub of strips per month supplied on prescription, supplementing that with buying the extra strips I needed myself. However, now that I have ceased diabetes medication I am told I no longer "qualify" for strips from the NHS so am thinking about swapping to Codefree. Any feedback much appreciated, thanks

Thanks @urbanracer I know there have been threads on this subject in the past so appreciate you replying
