Anyone own a Sannuo Yizhun GA-3 ?

[RichardHawkings]

I just got this from China, via Lazada. It has many very good reviews, but I'm a little surprised at my readings (happy, but surprised)... Fasting 4.7, postprandial 3 hours 4.9

Does anyone else have one and can confirm it is accurate?

The only way to confirm your meter as accurate would be to use a test solution, available online or if you fancy a bit of diy....
