It is not original Greenwon AT-868F, it is a copy model. No serial number and no model name. Accuracy is poor, if you try three times measure, it will get three different results. It is only useful to check if you have ZERO alcohol in your blood and can go drive or not, do not trust this machine for right alcohol level. Disappointed with the producy

I don’t think this product is reliable; if you test three times in a row you get three different results. Not original Greenwon brand as stated by the seller
