Very useful product.
12 days in Slovakia, pleasant little precision alcohol tester
The device is functional, the function of monitoring the minimum permissible concentration of alcohol is very sensitive. For fans to compete in the amount of drink is not suitable categorically
Working very good for my needs. 😉
I have ordered 2 pieces. One of them works well, but unfortunately the display of the other one remains dark. Every attempt to start it has failed.... How can I fix this problem?

Super
fairly easy to use and repeated several times in a row and measures the same values that were measured by different people at the moment. Delivered via EU priority line in a whopping 5 days super.
