Attention! This device displays incorrect results! Had bought on the advice of my family doctor me the device. My sober values were always within the range between 75 and 85, why did I then made me stop worrying. When retested at the doctor, a significantly higher value came out again. I've then another instrument can give to right in practice and tested in parallel with a few days two instruments. The unit of "Breuer" always consistently indicated a value that was lower 20-25 mg / dl than my actual value. This is very fatal for patients suffering from diabetes People !!!! Have then written directly to Breuer. Waiting until today for an answer ..... can only advise to buy this device !!!
