However, my first measurement showed good 30mg / dL (!) Contrast to the comparative measurement of Avira. But it occurred to me at once that I let the patrol are eternally long (15min?), While I was studying the instructions for use. After the instructions I have the patrol after I took them out of the can, use in 3 minutes. So I took a new patrol and this time the result was almost exactly the same (difference 1mg / dL) as at Avira.
After I now know that I can take the patrol shortly before measurement of the can, all measurements were running properly. Because of the favorable rates I measure more often and can thus better control my sugar levels.
From the manufacturer's website, I got even a program for recording the values, but there is a lack of data cable to unterzuladen the data from the device to PC. I would be grateful if the seller this data cable would offer here in Amazon.
